SUBSTANCE: invention relates to computing. The effect is achieved by performing (i) distributed structural and algorithmic transformations, at the final (i+1) stage of which the generated data stream, represented by a binary code, is converted into direct and inverse ternary codes with symbols that are represented in the form of pulse-width modulation (PWM₃), wherein each of the received PWM₃ substreams is summed with a meander pulse sequence, with a period T₀ equal to the duration of the original binary symbols, and taking values "+1" and "-1", as a result of which a bipolar pulse sequence is obtained in each of the substreams, which is then divided into even and odd symbols with the formation of semi-streams in each of the substreams; upon reception, the transition from the extended in phase modulation symbols of the in-phase and quadrature components to the accelerated initial representation is obtained using a gate "inhibit", to the inhibiting input of which a square wave signal is supplied; the half-streams in each of the substreams are combined, the generated original substreams are summed with the inverted meander, as a result of which the PWM₃ pulses of the original direct and inverse ternary codes are restored, after which, based on the obtained redundancy, transmission errors are detected and corrected at the symbol level of ternary codes.

Description

The invention relates to telecommunication systems and can be used in data transmission systems over communication channels. Its use makes it possible to increase the reliability of information transfer without introducing structural redundancy into the transmitted messages, to detect errors occurring during transmission, both single and multiple, to increase, if necessary, the speed of information transfer and ensure its secrecy.

The invention relates to a new direction in the development of data transmission systems. It is based on dividing the original data stream of the transmitted information into substreams and orthogonal quadrature subcarriers corresponding to them at the modulation stage. The main option for their subsequent use is associated with their next combination before transmission to the communication channel with the formation of a total signal with a complex carrier frequency:

where A _I and A _Q are the in-phase and quadrature components of the harmonic oscillations of the circular frequency ω = 2πf.

In this case, the output signal A is formed as a result of the summation of two harmonic oscillations shifted relative to each other by 90 ° and having the same frequency f. Their sum also represents the original oscillation with the carrier frequency of the radio signal, but with a phase shift by an angle equal to ϕ = arc tan (A _Q / A _I ). When receiving such a sum signal, for their reverse division into in-phase I and quadrature Q components, algorithms of direct and inverse fast Fourier transform are used.

This technology is called: Orthogonal Frequency-Division Multiplexing (OFDM) ([1], Shakhnovich IV "Modern technologies of wireless communication", M .: Technosphere, 2006. - 288 p, pp. 75-80). The essential characteristics of the proposed invention are in the use of three-basic error-correcting coding, which is adapted to the existing OFDM technologies, focused on the original traditional binary coding of the transmitted information.

Known methods for generating replacement three-level codes, which are used in cable communication lines to allocate on the receiving side of the timing oscillation, which is necessary to improve the accuracy of the symbol synchronization of the data stream recovered in regeneration points (RP).

Among the three-level codes, the most common is a compatible bipolar code with high density (KVP-n, CHDB-n - in the English interpretation) ([2], Levin LS, Plotkin MA "Digital information transmission systems." - M .: Radio and communication, 1982. - 216 s, p. 135-143). In accordance with the algorithm for generating KVP-n codes [1], an illustration of which is shown in FIG. 1 sequence of (n + 1) symbols "0" of the binary code <000 ... 000> _{2 is} replaced with code combinations <000 ... 00V> ₂ and <000 ... B0V> ₂ , where V is a pulse, the polarity of which repeats the polarity of the preceding code pulse, and B - on the contrary, represents a pulse in the formed sequence, the polarity of which is opposite with respect to the polarity of the previous pulse. FIG. 1 is an initial bit sequence and an illustration for explaining the basic principles of high density code (HCD) generation (FIG. 1 (B)). As shown in FIG. 1 (B) of the illustration, it follows that: 1) information pulses with a change in their polarity are used only when transmitting symbols "1"; 2) their duration (τ ₀ ) is halved compared to the duration (T ₀ ) of the symbols “1” and “0” of the original binary code (τ ₀ = 1 / 2T ₀ ). In the case of data transmission using radio channels, the transition from the binary code to the known three-level codes is not justified, since reducing the duration of the pulses corresponding to the symbols "1" and "0" of the binary code is in conflict with the limitation imposed on their bandwidth. At the same time, when they are used in fiber-optic communication lines (FOCL), such a decrease does not become critical, since there are no problems associated with the need to provide the required bandwidth.

Known "Methods for transferring information and systems for their implementation" ([3], patent RU No. 2475861 with a priority of 04/27/2013 and [4]), patent RU No. 2581774 with a priority of 09/30/2014) the essential characteristics of which are concluded in the transition in the transmission of information from the traditionally used binary code with the symbols "1" and "0" to the replacement logical ternary error-correcting coding with the symbols S ₂ , S ₁ and S ₀ , represented by three allowed values of pulse-amplitude modulation (PAM3), which are duplicated by symbols T ₂ , T ₁ and T ₀ , representing the three allowed values of pulse width modulation (PWM ₃ ).

In the patent [4], which was awarded the Rospatent diploma in the nomination "100 best inventions of Russia - 2016", the proposed ternary code with symbols S ₂ (T ₂ ), S ₁ (T ₁ ) and S ₀ (T ₀ ) was used according to a new purpose - to increase the information load of the carrier frequency emitted by the transmitter, for which simultaneous (complex) modulation in amplitude, frequency and phase was used. In addition, the “comparability of the results of demodulation of relative phase modulation (OFM) with base two, used over the main communication channel, and the proposed ternary phase modulation with base two (PM ₂ ³ ), which is based on logical noise-immune codes with base three, presented symbols S ₂ (T ₂ ), S ₁ (T ₁ ) and S ₀ (T ₀ ) "(claim 4 of the claims). However, to implement such a possibility, an additional (duplicate) information transmission channel is required, which cannot always be provided in a variety of practical applications. The essence of the proposed logical error-correcting coding of generated messages by a substitute ternary code is as follows [3] and [4].

The analogous methods [3] and [4] are based on transformation formulas Г related to the replacement of a sequence of symbols a _i0 , a ₁ , ..., a _{in of the} binary alphabet A = {0,1} with sequences of symbols d _i0 , d _i1 , ..., d _im alphabet D = {00, 11, 10, 001, 101} based on the following logical encoding schemes:

The proposed encoding establishes a logical correspondence between the binary characters represented in parentheses and their ternary equivalents S ₀ , S ₁ and S ₂ . As a result of the technical implementation proposed in patents [3] and [4], ternary symbols S ₀ , S ₁ and S ₂ at the stage of primary (pulse) modulation are converted into signals with amplitude-pulse modulation (PAM ₃ ). In this case, the time intervals between them also have the corresponding three values of the duration T ₀ , T ₁ = 1.5T ₀ and T ₂ = 2T ₀ , where T ₀ is the duration of the symbols "1" and "0" of the original binary code used for the initial representation transmitted information. These three durations represent, in turn, signals with pulse width modulation (PWM ₃ ). Further, at the stage of secondary modulation, the signals presented in the form of AIM ₃ are converted into frequency modulation (FM ₃ ), and the time moments of changing the PWM ₃ pulses are represented by changing the phases of the carrier frequency by 0 ° and 180 °, which corresponds to the simplest form of phase shift keying into two states (PM ₂ ) or relative phase modulation (OFM ₂ ).

и

):The algorithm for translating a sequence of binary symbols "1" and "0" into the proposed direct ternary code is as follows. Suppose it is necessary to translate the following sequence of binary characters <10101000111100101> ₂ with the number of characters equal _{to the new alphabetic coding: N 2} = 17. For this purpose, conditional upper and lower partitions are used (

presented to facilitate understanding of the basic logical rules for the transition from binary code to the proposed forward ternary coding. For this purpose, the transcoding process is depicted in different colors. As a result of their combination (

U

) the following sequence of symbols of the direct ternary code is obtained: S ₂ S ₂ S ₁ S ₀ S ₁ S ₀ S ₀ S ₀ S ₁ S ₁ S ₂ with the number of symbols N ₃ = 11.

The following conclusions follow from the above illustration:

1) the new ternary code is a recurrent economical error-correcting code, in which the last binary symbol "1" or "0" decoding the previous ternary symbol S _ij , where i is the base of the code (i = 0,1,2), is the first one when decoding the next ternary symbol S _{ij + 1} ;

2) its efficiency (k) is determined by the fact that the number of ternary symbols required to transmit the same amount of information is, on average, less than k ₃ = log ₂ 3 = 1.6 times (for the given example, k = 17/11 = 1.54).

The technical implementation presented in patents [3] and [4] makes it quite easy to implement the transcoding process. In addition, in this case, it becomes possible to represent data at the level of primary pulse modulation by duplicating each other ternary symbols S _i using PWM ₃ and symbols T _i , which are converted into pulse width modulation PWM ₃ .

In the proposed invention, correspondence (1) is supplemented with an inverse version of its formation, when the following inverse binary code constructions are matched to the _{signals S 0} * (T ₀ ), S ₁ * (T ₁ *) and S ₂ * (T _{2 *):}

where the broken brackets <010> ₂ denote the binary number system (Fig. 2).

It follows from it that the recoding from the binary code into the proposed ternary code is implemented according to the same logical rules considered earlier. The difference is manifested only in the assignment of the ternary symbols S ₁ * (T _i *) to inverse code binary structures that appear in the stream of the encoded bit sequence.

Thus, in the proposed invention, the essential characteristics are as follows:

1) in additional use, in addition to coding using a replacement direct logical noise-immune ternary code, its inverse analogue, the encoding and decoding process of which is determined by the correspondence (2);

2) in the use of ternary code to modernize the existing methods of quadrature modulation of the carrier frequency of the radio signal.

The closest analogue to the claimed method is a prototype patent ([5], "Method for transmitting information using a substitute logical ternary error-correcting code", application No. 10/09/2020).

It consists in collecting signals from message sources, synchronizing them in time, forming a compressed digital group signal from synchronized collected signals, generating a carrier frequency signal, modulating the carrier frequency signal with a compressed digital group signal based on the generated video code, and then transmitting the modulated signal over a communication channel , characterized in that on the transmitting side, digital messages of information sources, represented by an N-bit positional binary code, are subjected to structural and algorithmic transformations carried out in the following sequence: first, additional economical coding, using the natural redundancy of the transmitted information to increase noise immunity, followed by a symbol randomizer binary code, the purpose of which is to equalize the probabilities of the appearance of the characters "1" and "0" at its output to approach the value equal to 0.5, after which The compressed digital group signal is encoded and encoded with an error-correcting code with the introduction of redundant check symbols, the obtained results of converting the digital group signal, represented by a binary code with the symbols "1" and "0", are converted into a replacement logical error-correcting code with the symbols "S ₀ " and " T ₀ "," S ₁ "and" T ₁ "" S ₂ "and" T ₂ ", while the binary combinations (" 00 "and" 11 ") of the original sequence of binary symbols are associated with simultaneously generated symbols of the ternary code" S ₀ "and" T ₀ ", the code combinations of the original binary code of the group signal (" 001 "and" 10 ") are replaced by the generated symbols of the ternary code" S ₁ "and" T ₁ ", and the code combinations remaining in the original sequence of the binary code of the group signal combinations of the form "101" are simultaneously put in a one-to-one correspondence with the symbols of the ternary code "S ₂ " and "T ₂ ", after which the first modulating component of the converted first tri-basic video signal containing the symbols "S ₀ "," S ₁ "and" S ₂ ", represent in the form of pulse-amplitude modulation, and the second modulating component of the video signal with the symbols of the three-base code" T ₀ "," T ₁ = 1.5T ₀ "and" T ₂ = 2T ₀ ", Where T ₀ is the duration of one symbol of the original binary code" 1 "and" 0 ", is used for bipolar pulse width modulation (PWM ₃ ), which is a second video signal, the pulses of which are with three allowed values: T ₀ , 1.5T ₀ and 2T ₀ take the values of the amplitudes and then they are summed with the clock synchronization signals, which are a bipolar meander with a period of its repetition T ₀ and the duration of each of the pulses T _0/2 and the values of the amplitudes, and as a result, a replacement tri-basic code is obtained, represented by a sequence of symbols "+2", "0" and "-2", each of which has a bipolar pulse duration equal to T _0/2 , as a result of which, in a new logical sequence, the idea of the original bipolar pulse width modulation (PWM ₃ ), But on the basis of symbols of the same duration T _0/2, instead of T _0, 2T, and 1.5T _{0 0,} then the generated logical sequence tribasic symbols "2", "0" and "-2" are divided into in-phase and quadrature substreams, the first of which is represented by odd-numbered symbols, and the second - by even-numbered symbols of the ternary code, then the duration of each of the symbols in the substreams with subsequent quadrature modulation of the carrier is doubled, while in the in-phase and quadrature substreams of the transmitted data a change the polarities of the extended pulses are represented by manipulating the phase of the carrier frequency by 0 ° and 180 °, corresponding to the cosine law for the in-phase component, and by changing the phase of the carrier frequency by 0 ° and 180 °, corresponding to the sine law for the quadrature component, on the receiving side, each of the received doubled in the result of quadrature modulation of binary code symbols belonging to the in-phase and quadrature streams of ternary code symbols and perceived as regular pulse code of the same length lead to their original predmodulirovannomu mean using a logical element "Prohibition", for which at its inhibit input supplied square wave signal with period T _0, and the duration of each pulse of T _0/2, the meander signals used in this case are inverted for the in-phase substream and a direct copy for the quadrature component, after which the received signals are summed, and as a result of this, the logical sequence of the three-base symbols "+2", "0" and "-2" is restored in the form in where it was formed on the transmitting side, which is then summed up with an inverted copy of the meander signal with a period T0 and a duration of each of the pulses T _0/2 for the subsequent transition to pulse-width modulated pulses of a three-basic logical noise-immune code with symbols "T ₀ ", "1, 5T ₀ "and" 2T ₀ ", control the reliability of reception based on the parity criterion of the symbol in "1.5T ₀ ", enclosed between adjacent symbols "2T ₀ ", with a positive result of control of the integrity and reliability of the information received, the tri-basic _{code with the symbols "T 0 ", "1.5T 0} " and "2T ₀ " is decoded into the original binary code based on the following correspondences: “T ₀ ” ↔ <11.00> ₂ , “1.5T ₀ ” ↔ <10.001> ₂ and “2T ₀ ” ↔ <101> ₂ and the established rule of recurrent relationship in which the last binary the symbol "1" or "0" of the previous decoding of the ternary code becomes the first character "1" or "0" of the decoding of the subsequent symbol of the ternary code "T ₀ ", "1.5T ₀ " and "2T ₀ ", when recovering these repeated symbols are combined , as a result of which the original bit sequence of the transmitted information is restored.

In the method [5], one of the possible options for using the direct ternary code for upgrading the existing methods of quadrature modulation of the carrier frequency of the radio signal is considered. The process of its formation is shown in Fig. 3 (A) and FIG. 3 (B). FIG. 3 (A) shows the original binary code, which is a sequence of 23 bits (a _i ), and FIG. 3 (B) the results of its replacement by a direct logical error-correcting ternary code using 17 symbols S _i , i = 0, 1, 2. FIG. 3 (B) the first 7 symbols S _i , i = 0, 1, 2 are represented by their corresponding duplicate symbols T ₀ , T ₁ = 1.5T ₀ and T ₂ = 2T ₀ , represented as PWM pulses ₃ . The essential characteristics of the patent [5] are applied to the PWM signals generated on the transmitting side ₃ (Fig. 3 (B)) and their received copies when receiving operations of addition and subtraction with a bipolar meander with amplitude values (+1) and (-1) (Fig. 3 (D)). As a result of this, a tri-basic code is formed on the transmitting side with a pulse duration equal to the duration T _{0 of the} symbols “1” and “0” of the original binary code, and with the values of the amplitudes: “+2”, “0” and “-2) (Fig. 3 (D)). Then the generated three-level code is divided at the level corresponding to the value "0" into in-phase (I) and quadrature (Q) components (Fig. 3 (E)) and (Fig. 3 (G)), respectively. Due to the fact that the duration of the pulses (Fig. 3 (E, E and G)) turned out to be the same and equal to T ₀ , it becomes possible to use algorithms for the direct and inverse fast Fourier transform when receiving to divide the total signal obtained by quadrature modulation into initial components: in-phase (I) and quadrature (Q).

In the proposed invention, an additional embodiment of the prototype patent [2] is used, when the same operations are performed in parallel with respect to the symbols of the inverse ternary code T ₀ * = T ₀ , T ₁ * = 1.5T ₀ and T ₂ * = 2T ₀ ... It assumes the use of decryptions, the rule for which is determined based on the correspondence (2). They are also shown in FIG. 4 in the same order as in FIG. 3. As a result of their combination, there appears a significant redundancy of the transmitted symbols of the forward T ₀ , T ₁ = 1.5T ₀ and T ₂ = 2T ₀ and inverse T ₀ * = T ₀ , T ₁ * = 1.5T ₀ and T ₂ * = 2T substitute ternary symbols, which follows from a comparison of the plots shown in FIG. 3 (F, G) and Fig. 4 (E, F).

So, when using the simplest error-correcting code with the repetition of the transmitted symbols of the binary code, duplicating each other, it will be necessary to increase their number by 2 times. For the example shown in FIG. 3 and FIG. 4 examples, their number will be: k ₂ = 23 × 2 = 46. If we use the proposed ternary code - direct and inverse, duplicating each other, then the number of transmitted symbols will increase under similar modulation conditions PWM ₃ -PM ₂ to the value k ₃ = 17 × 2 = 34. The ratio k ₂ / k ₃ is: 1.35, therefore, the introduced redundancy is 35%, instead of 100% when using the error-correcting code with the repetition of the transmitted symbols of the binary code. In this case, the following additional features will appear, which the closest analogue does not have - an error-correcting code with a repetition of the transmitted symbols of a binary code:

1) reduction of distortions in the implementation of signal + interference due to substitution when receiving an undistorted meander signal generated on the receiving side on the basis of the recovered synchronization signals (Fig. 5);

2) detection and correction of errors at the level of the signal + interference realization restored upon receipt (Fig. 5);

3) detection and correction of errors due to the fact that symbols T ₀ ↔ (00.11) of the direct code and symbols T ₀ * ↔ (11.00) of inverse ternary coding will appear in the same places, both during coding and decoding the transmitted information.

In addition, there is one more additional rule for controlling the reliability and integrity of information at the symbolic level. It consists in the fact that in the received stream between adjacent symbols T ₂ ↔ (101) there should be only an even number of symbols T ₁ ↔ (10,001) when using the direct ternary code, which is used in the prototype patent [5]. But the same rule for checking the validity and integrity of information at the symbolic level is also fulfilled when using the inverse ternary code: in the received stream between adjacent symbols T ₂ * ↔ (010) there should be only an even number of symbols T ₁ * ↔ (01,100). As a result, the control of the reliability and integrity of information will become cross and, as a result, more complete, due to which there will be a new opportunity not only to detect, but also to correct data transmission errors.

Further, to eliminate the unmasking signs of the presence of a ternary code during quadrature modulation, the generated three-level inverse code is also divided at the level corresponding to the value "0" into in-phase (I) and quadrature (Q) components (Fig. 4 (E)) and (Fig. 4 (G)), respectively. The resulting reserve time in each of the generated substreams is used, as provided in the classical theory of quadrature modulation, to expand the duration of the generated pulses of the ternary code (Fig. 4 (D)): they become equal to T _p ^kv = 2T _i , i = 0, 1, 2, as shown in FIG. 5 (B) for the case of using direct ternary coding. As a result of this, the unmasking feature of the proposed ternary code, consisting in the duration of the PWM ₃ equal to T ₁ = 1.5T ₀ , disappears during reception, since this duration after doubling the duration becomes equal to an integer T ₀ equal to 3.

The resulting two variants of logical error-correcting coding using direct and inverse ternary replacement coding are transmitted using dedicated carrier frequencies f _n and f _in , or at subcarriers: f _n = f ₀ - Δf and f _in = f ₀ + Δf, where f ₀ - the carrier frequency of the radio signal.

When receiving, the reverse operation of restoring the transmitted symbols of the inverse ternary code T ₀ * = T ₀ , T ₁ * = 1.5T ₀ , T ₂ * = 2T ₀ , where T ₀ is the time duration of the symbols "1" and "0" of the original binary code , does not differ from the same operations that are performed when restoring direct ternary code. The difference lies only in the assignment by the restored symbols of the inverse ternary code T ₀ * = T ₀ , T ₁ * = l, 5T ₀ , T ₂ * = 2T ₀ inverse code combinations of the original binary code, which, according to the coding condition, are assigned to them (2) ...

As a result, the noise immunity of the transmitted signals will be increased, in addition to detecting and correcting data transmission errors, according to such a sub-indicator as the secrecy of the transmitted information. Another component of this technical effect, as noted earlier, is due to the fact that the noise immunity of the meander restored on the receiving side will be significantly higher than the received signal, since it is formed on the basis of the reception of synchronization signals, to a similar indicator of which, in accordance with the communication theory higher requirements are imposed.

The main disadvantage of replacing the primary pulse-code modulation of a binary code (CMM ₂ ) with PWM ₃ when using the proposed three-base code is the different duration of the ternary symbols T _i , i = 0, 1, 2: T ₀ , 1.5T ₀ and 2T ₀ instead of the original value T ₀ will also be excluded. It is also necessary to ensure continuity with existing methods of information transmission, including operations that are focused only on binary symbols that have the same duration in time T ₀ . These include, for example: Fast Fourier Transform (FFT) operations and existing technologies for using pseudo-randomly hopping radio frequencies (PRHF), which form the basis for expanding the spectrum of radio signal frequencies and providing, on this basis, the secrecy and security of transmitted information.

As a result of the analysis, it becomes possible to form the following refined claims.

by even counting symbols of the ternary code, then the duration of each of the symbols in the substreams with the subsequent quadrature modulation of the carrier is doubled, while in the in-phase and quadrature substreams of the transmitted data, the change in the polarity of the extended pulses is represented by manipulating the phase of the carrier frequency by 0 ° and 180 °, corresponding to the cosine law for the common-mode component, and a change in the phase of the carrier frequency by 0 ° and 180 °, corresponding according to the sine law for the quadrature component, on the receiving side, each of the received binary code symbols spread twice as a result of quadrature modulation, belonging to the in-phase and quadrature streams of ternary code symbols, perceived as ordinary pulse symbols of the same duration, are reduced to their original pre-modulated form with using a logical element "Prohibition", for which at its inhibit input supplied signals meander with a period T ₀ and the duration of each pulse of T _0/2 used in this meander signals are inverted for phase substream and a direct copy of the quadrature component, then the received the signals are summed, and as a result, the logical sequence of the three-basic symbols "+2", "0" and "-2" is restored in the form in which it was formed on the transmitting side, which is then summed with an inverted copy of the meander signal with a period of T ₀ and the duration of each of the impulses ₀ to T / 2 for subsequent transition to a pulse-modulated pulses tribasic logical error-correcting code with symbols "T _{0", "0} 1.5T" and "2T _0", control is performed based on the reception reliability criterion parity symbol "1.5T ₀ "Enclosed between adjacent symbols" 2T ₀ ", with a positive result of integrity control and reliability of the information received, the inverse transformation of the three-base code with the symbols" T ₀ "," 1.5T ₀ "and" 2T ₀ "into the original binary code is performed based on the following matches: “T ₀ ” ↔ <11.00> ₂ , “1.5T ₀ ” ↔ <10.001> ₂ and “2T ₀ ” ↔ <101> ₂ , the established rule of recurrent relationship, in which the last binary character is “1” or "0" of the previous decoding of the ternary code becomes the first character "1" or "0" of the decoding of the subsequent symbol of the ternary code "T ₀ ", "1.5T ₀ " and "2T ₀ " the original bit sequence of the transmitted information mation, characterized in that at the same time on the transmitting side a similar, but inverse ternary compressed error-correcting code with duplicate symbols S _i * (T _i *), i = 0, 1, 2, is formed in accordance with the same logical rules, use the same binary code constructions, but with the inverse designation of the symbols of the binary code, when symbols S ₀ * (T ₀ *) are associated with a combination of a binary code ("11" and "00") of the original sequence of binary symbols, symbols S ₁ * ( T ₁ *) correspond in the original sequence of the binary code combinations ("01" and "110"), and the symbols S ₂ * (T ₂ *) correspond to the code structure "010" of the original sequence of the binary code of information to be transmitted at the stage of primary modulation carry out operations similar to those that are implemented with respect to the sequence of the direct ternary code with duplicate symbols S _i (T _i ), i = 0, 1, 2, as a result of which the symbols of the inverse ternary code S _i *, i = 0, 1, 2 is converted into pulse-amplitude modulation with three allowed states corresponding to the indices i = 0, 1, 2, and the corresponding duplicate symbols of the inverse ternary code T _i *, i = 0, 1, 2, are converted into pulse-width bipolar modulation with the values of the amplitudes of the signals "+1" and "-1", which take the following three permitted pulse durations: T ₀ * = T ₀ , T ₁ * = 1.5T ₀ , T ₂ * = 2T ₀ , which, as well as similar symbols of the direct ternary code T _i , i = 0, 1, 2, is subjected to the same additional operations: meander pulse modulation based on summation with the same clock synchronization signals, which are a bipolar meander with a repetition period T ₀ and a duration of each of the pulses T _0/2 and the values of the amplitudes and with obtaining at the output of the replacing inverse tri-basic code represented by a sequence of three-level symbols "+2", "0" and "-2", which are divided by the level corresponding to the value "0" of the formed three-level and pulse signal, as a result of which the in-phase and quadrature components are obtained, the duration of which is doubled, while the moments of the beginning and end of the pulses at the secondary modulation stage are represented by the change in the phase values of 0 ° and 180 ° of the subcarriers corresponding to the in-phase and quadrature substreams, are summed with the formation of a complex data stream, which is transmitted over the corresponding radio channel.

As an additional explanation of the essence of the invention, the following should be noted.

The in-phase component I (t), in accordance with the principles of quadrature modulation of the carrier frequency of a radio signal [6], is represented by a cosine law of change in its values, and the quadrature component Q (t) turns out to be phase-shifted by π / 2 = 90 ° and correspond to the sinusoidal law of change in the carrier radio frequencies. Each of the impulse components controls the phase change law of 0 ° and 180 ° of the carrier radio frequency, but due to their shift relative to each other by π / 2 = 90 °, it turns out that each of their modulation states differs by π / 4 = 45 °, which shown in the illustration of FIG. 6 and FIG. 7.

Three-base code with symbols T _i and T _i *, i = 0, 1, 2: T ₀ , T ₁ = 1.5T ₀ , T ₂ = 2T ₀ and T ₀ * = T ₀ , T ₁ * = 1.5T ₀ , T ₂ * = 2T ₀ , is detected only after using the "Disable" operations, the use of which refers to the inverse operation intended for removing the meander modulation (meander demodulation) (Fig. 5).

This new scientific direction in the synthesis of complex noise-like signals, structure-code and signal-code structures has been actively developing recently under the name "meander noise-like signals (BOS signals)", which are designed to increase the efficiency of satellite radio navigation systems [7] (M. S. Yarlykov "Meander noise-like signals (VOS signals)" and their varieties in satellite radio navigation systems, Moscow: Radiotekhnika, 2017. - 416 p.).

In this invention, as in the prototype method, meander technologies were used for a new purpose - to provide comprehensive information protection when using the method of economical noise-resistant data coding based on replacement logical ternary codes.

On the receiving side, doubled pulses of the reconstructed in-phase and quadrature components of the ternary code, differing from similar diagrams given for the transmitting side, only by the influence of interference. Their amplitudes take two values 1 and 0, which are converted into changes in the phase of the radio signal 180 ° and 0 °.

Similarly, two times widened pulses of the quadrature channel Q (t) of the ternary code are restored

The resulting restored straight line T ₀ , 1.5T ₀ , 2T ₀ and inverse T ₀ * = T ₀ , T ₁ * = 1.5T ₀ , T ₂ = 2T ₀ ternary codes identified with PWM ₃ and PWM ₃ * pulses that are subject to various kinds of transmission distortions will be recovered with a higher quality. In addition, the transmitted images (or semifinished products in accordance with the explanation used in [5]) of the transmitted character sequence will be restored in their original form only upon receipt of information. This is also the fundamental difference and essential characteristics of the proposed invention. Thus, the transmitted information at the structural-code level will be additionally protected from interference, unauthorized access (NSD) and information technology impacts (ITV).

Distinctive features of the proposed invention are also associated with the need to combine various structural and algorithmic transformations (SAP) related to coding and modulation of signals into a single consistent information system, which forms the basis for the synthesis of various problem-oriented structural code (STC) and signal-code structures (CCC) ). A new direction in the development of innovative technologies is to make maximum use of the possibilities of additional programming of the modern element base, which forms the basis for the creation of telecommunication systems (TCS). In this case, their hardware component may remain the same, not subject to changes, and its new capabilities are provided by the implementation, based on reprogramming of FPGAs, microcontrollers and microprocessors that are part of the TCS, new compression algorithms, randomization, additional noise-immune coding and modulation.

2. The method according to claim 1, characterized in that on the transmitting side, the obtained results of converting the digital baseband signal, represented by a binary code with the symbols "1" and "0", are converted, in addition to the direct copy, into an inverse replacement logical error-correcting code with the symbols S ₀ * and T ₀ *, S ₁ * and T ₁ *, S ₂ * and T ₂ *, while the binary combinations ("00" and "11") of the original sequence of binary symbols are associated with the simultaneously generated symbols S ₀ * and T ₀ * of the inverse ternary code and symbols S ₀ and T _{0 of the} direct ternary code, the code combinations of the original binary code of the group signal ("01" and "110") are replaced by the generated symbols of the inverse ternary code S ₁ * and T ₁ *, and the remaining in the original sequence of the binary code of the group signal, the code combinations of the form "010" are simultaneously put in a one-to-one correspondence to the symbols of the inverse ternary code S ₂ * and T ₂ *, after which the first modulating component of the converted first inverse tr e of the main video signal, containing the symbols S ₀ *, S ₁ * and S ₂ *, are represented in the form of pulse-amplitude modulation, and the second modulating component of the video signal with symbols of the _{tri-basic code T 0} * = T ₀ , T ₁ * = 1.5 T ₀ and T ₂ * = 2T ₀ , where T ₀ is the duration of one symbol of the original binary code "1" and "0", is used for bipolar pulse width modulation (PWM ₃ ), which is a second video signal, the pulses of which with three allowed values: T ₀ * = T ₀ , T ₁ * = 1.5T ₀ and T ₂ * = 2T ₀ take the values of amplitudes "+1" and "-1", then they are summed up with clock synchronization signals, which are a bipolar meander with a period of its repetition T ₀ and the duration of each of the pulses T _0/2 and the values of the amplitudes "+1" and "-1", as a result of which a replacement inverse three-base code is obtained, represented by a sequence of symbols "+2", "0" and "-2", each of which has a bipolar pulse duration equal to T _0/2 , as a result of which, in a new logical position Inverse ternary code sequences retain the idea of the original bipolar pulse width modulation (PWM ₃ ), but based on symbols of the same duration T0 / 2, instead of T ₀ * = T ₀ , T ₁ * = 1.5T ₀ and T ₂ * = 2Т ₀ , after which the generated logical sequence of three-base symbols "+2", "0" and "-2" is divided into in-phase and quadrature substreams, the first of which is represented by odd symbols, and the second - by even counting symbols of the ternary code, then the duration of each symbol in the substreams with the subsequent quadrature modulation of the carrier is doubled, while in the in-phase and quadrature substreams of the transmitted data, the change in the polarity of the extended pulses is represented by manipulating the carrier phase by 0 ° and 180 °, corresponding to the cosine law for the in-phase component, and changing phase of the carrier frequency by 0 ° and 180 °, corresponding to the sine law for the quadrature component, as a result of which the generated and transmitted along the pa diochannel, the common signal with quadrature modulation in its appearance will not have any fundamental differences from existing analogs using a binary code with symbols "1" and "0" as a basis, on the receiving side each of the received double-widened binary code symbols as a result of quadrature modulation , belonging to the in-phase and quadrature streams of ternary code symbols, perceived as ordinary pulse symbols of the same duration, lead to their original pre-modulated form using the "Inhibit" logic element, for which meander signals with a period T ₀ and a duration are fed to its inhibiting input each of the pulses ₀ T / 2 used in this meander signals are inverted for phase substream and a direct copy of the quadrature component, then the received signals are summed, and the resulting reduced tribasic logical sequence of symbols, "two", "0" and " -2 "in the form in which it would be yla is formed on the transmitting side, which is then summed with the inverted replica meander signal with a period T0 and a duration of each pulse of T _0/2 for subsequent transition to a pulse-modulated pulses (PWM ₃₎ inverse tribasic logical error-correcting code with symbols T ₀ *, T ₁ * = 1.5T ₀ and T ₂ * = 2T ₀ , the reliability of reception is monitored based on the parity criterion of symbols T ₁ * = 1.5T ₀ , enclosed between adjacent symbols T ₂ * = 2T ₀ , with a positive result of integrity control and the reliability of the information received, the three-base code with symbols is decoded into the original binary code based on the following correspondences: T ₀ * = T ₀ ↔ <00.11> ₂ , T ₁ * = 1.5T ₀ ↔ <01.110> ₂ and T ₂ * = 2Т ₀ ↔ <010> ₂ and the established rule of recurrent relationship, in which the last binary character "1" or "0" of the previous decoding of the ternary code becomes the first character "1" or "0" of the decoding of the subsequent character of the ternary code T ₀ * = T ₀ , T ₁ * = 1.5T ₀ and T ₂ * = 2T ₀ , during restoration these repeated symbols are combined, as a result of which the original sequence of bits of the transmitted information is restored.

As a result of such an addition, it becomes possible to carry out extended control of the reliability and integrity of the information received.

3. The method according to claim 1, characterized in that they provide double control of the reliability and integrity of the received information at the symbolic level, which consists in the fact that in addition to the basic rule determined by the presence of an even number of symbols S ₁ (T ₁ ) ↔ <10, .001 > ₂ in the time interval Δt _s between the received adjacent symbols S ₂ (T ₂ ) ↔ <101> ₂ when using a direct logical ternary code with symbols S _i (T _i ), i = 0, 1, 2, use the same rule and with respect to the generated inverse logical ternary code with symbols S _i * (T _i *), i = 0,1,2, assuming the presence of an even number of symbols S ₁ * (T ₁ *) ↔ <01,110> ₂ on the corresponding time interval Δt _s between the received adjacent symbols S ₂ (T ₂ ) ↔ <010> ₂ , as a result of which the control of the reliability and integrity of the received information becomes cross, complementary, while the second rule of the reliability and integrity of the received information is also applied at the symbolic level, which is in detecting the recurrence of symbols S ₀ (T ₀ ) ↔ <11,00> ₂ and S ₀ * (T ₀ *) ↔ <00,11> ₂ in the forward and inverse logical ternary codes, which makes it possible not only to detect distorted by interference ternary symbols, but also correct transmission errors.

The needs of the existing practice of information transfer, taking into account new economic conditions, require that, on the one hand, all new information technologies are quickly introduced, which is often hampered by the basic technical solutions implemented in existing practice, and at the same time, the modernization of existing systems and complexes should be minimal. cost. In conditions of such contradictions, those technical solutions that involve the introduction of a minimum of corrections at the hardware level into already existing systems and complexes acquire special significance. As a rule, traditional methods cannot be used to resolve such contradictions, therefore, a special urgency is felt in the search for various non-traditional reserves. They are based on the establishment of new relationships, both logical and analytical, including between new types of modulation that appear during the transition from a binary code to a more economical logical ternary code. A possible subsequent variant of their development is covered by a patent ([8], "A method for transmitting information using a substitute logical ternary error-correcting code", patent RU No. 2724794, publ. 06/25/2020, bul. No. 18). In it, PWM pulses _{3 of a} logical noise-immune ternary code are used as the basis for the transition from narrowband communication to broadband principles of its organization, based on their filling with "chips", which are Barker codes of length 7, 5 and 3 (Fig. 8 (a)). They fill the corresponding PWM pulses ₃ , having durations "T ₂ = 2T ₀ ", "T ₁ = 1.5T ₀ " and "T ₀ " (Fig. 8 (d)), respectively, and instead of appearing when using "chips" guard intervals with a duration of T0 / 4 substitute the binary symbol "1". The resulting binary code structures "101" with a symbol duration τ = T _0/4 are used for one of the operations of restoring the sequence of transmitted PWM pulses ₃ . Additional coding of the transmitted information by the proposed duplicate inverse ternary code creates the basis for enriching the idea of transition from narrowband to broadband in cases where the level of interference will lead to unacceptable losses when using narrowband information transmission.
