In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., the X, Y, and Z axes) may be determined by gyroscope sensor 180B. The gyro sensor 180B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 180B detects a shake angle of the electronic device 100, calculates a distance to be compensated for by the lens module according to the shake angle, and allows the lens to counteract the shake of the electronic device 100 through a reverse movement, thereby achieving anti-shake.

The temperature sensor 180J is used to detect temperature. In some embodiments, electronic device 100 implements a temperature processing strategy using the temperature detected by temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 performs a reduction in performance of a processor located near the temperature sensor 180J, so as to reduce power consumption and implement thermal protection. In other embodiments, the electronic device 100 heats the battery 142 when the temperature is below another threshold to avoid the low temperature causing the electronic device 100 to shut down abnormally. In other embodiments, when the temperature is lower than a further threshold, the electronic device 100 performs boosting on the output voltage of the battery 142 to avoid abnormal shutdown due to low temperature.

The touch sensor 180K is also referred to as a "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen". The touch sensor 180K is used to detect a touch operation applied thereto or nearby. The touch sensor can communicate the detected touch operation to the application processor to determine the touch event type. Visual output associated with the touch operation may be provided through the display screen 194. In other embodiments, the touch sensor 180K may be disposed on a surface of the electronic device 100, different from the position of the display screen 194.

In the second section, a signal transmission control method, a signal transmission control system and a related apparatus disclosed in the embodiments of the present application are described as follows.

In the related art, as shown in fig. 3, the bluetooth signal receiving method is a low-intermediate frequency receiving scheme, that is, a receiver sends a received radio frequency signal to a mixer for down-conversion after passing through a Low Noise Amplifier (LNA), and the down-converted radio frequency signal becomes a low-intermediate frequency signal after down-conversion, and then the low-intermediate frequency signal is filtered by an analog low-pass filter and enters an analog-to-digital conversion (ADC) module for sampling into a digital signal. For the digital low-intermediate frequency signal, a digital front end module (DFE) may perform digital down-conversion to obtain a baseband signal, and then the baseband signal is sent to a demodulation module for demodulation processing to obtain signal content. According to the scheme, the baseband signal is not directly obtained from radio frequency down conversion, so that the received signal is not influenced by direct current offset.

In practical applications, due to the gradual increase of data rate requirements of bluetooth related applications, the bluetooth signal format is also evolving towards higher transmission rates, from the bluetooth basic rate (BR, gaussian Frequency Shift Keying (GFSK) modulation) format, which initially provides 1Mbps transmission rate, to the subsequent bluetooth low power consumption (BLE), BLE2M, bandwidth of 2mhz, GFSK modulation) mode and bluetooth Extended Data Rate (EDR), EDR3M, preamble and signal header using GFSK modulation, and payload using 8DPSK modulation) format, which provide 2/3Mbps transmission rate, all of which are adapted to the current demand for high rate.

From the two higher rate formats (BLE 2M, EDR 3M), there are two ways for bluetooth to increase the transmission rate of the physical layer in the future: 1. higher order modulation schemes (e.g., 8 PSK); 2. a larger signal bandwidth.

However, the related art low intermediate frequency reception scheme receives a signal of a larger bandwidth requiring a very large analog low pass filter to be designed: for example, for a signal with a bandwidth of 4MHz, the low-intermediate frequency reception scheme needs to be at least selected at a frequency point of +3MHz, which requires designing an analog low-pass filter with a passband of-12 MHz, as shown in fig. 4, which is much larger than the actual signal bandwidth, and causes that much noise and interference cannot be filtered, thereby affecting the subsequent reception performance.

Further, referring to fig. 5 for solving the defects of the related art, fig. 5 is a schematic flowchart of a signal transmission control method provided in an embodiment of the present application, and is applied to a receiving device, where the receiving device is shown in fig. 1 or fig. 2, and as shown in the drawing, the signal transmission control method includes:

501. a target data rate of a signal format of a signal transmitted by a transmitting device is determined, the signal including a preamble signal and a data signal.

In this embodiment, the signal may be a communication signal of at least one communication mode, for example, the signal may include at least one of the following: bluetooth signals, infrared signals, ultraviolet signals, mobile communication signals (2G, 3G, 4G, 5G, 6G, etc.), ultra Wideband (UWB) signals, near Field Communication (NFC) signals, visible light signals, millimeter wave signals, etc., without limitation.

In this embodiment, a sending device and a receiving device may communicate with each other, and the sending device may send a signal to the receiving device, where the signal may include a preamble signal and a data signal, where the data signal may carry signal content, and the preamble signal is a signal for performing time synchronization between the sending device and the receiving device.

In a specific implementation, different signals correspond to different signal formats, different signal formats correspond to different data rates, and the data rate also corresponds to the transmission rate, for example, the larger the data rate is, the larger the transmission rate is.

Specifically, for example, the data rate of the bluetooth signal may be determined by the signal format of the bluetooth signal.

Optionally, as shown in fig. 6, the signal further includes: a guard interval;

the guard interval is located between the preamble signal and the data signal, and the guard interval is used for separating the preamble signal from the data signal.

Wherein the guard interval may enable a smooth transition between the preamble signal and the data signal.

In a specific implementation, the preamble signal may include: the method comprises the steps of a preamble, an access code and a signal head, wherein the preamble is used for estimating power and automatic gain; the access code is used for realizing timing synchronization; the signal head is used for carrying demodulation information. The data signal may include: the system comprises a synchronous code, a load and tail bits, wherein the synchronous code is used for realizing fine synchronization, the load is used for carrying signal content, and the tail bits are required by a format.

For example, in fig. 6, taking the bluetooth signal as an example, the bluetooth signal includes a preamble signal (GFSK, 1MHz bandwidth) and a data signal (8psk, 4MHz bandwidth), the preamble signal includes a preamble, an access code and a signal header, the data signal includes a synchronization code, a payload and tail bits, and the preamble signal and the data signal are separated by a guard interval.

502. And determining a target receiving mode corresponding to the target data rate, and receiving the preamble signal and the data signal according to the target receiving mode, wherein the target receiving mode is a receiving mode corresponding to a digital front-end module.

In the embodiment of the application, different receiving modes are set for different data rates, and the receiving mode is a receiving mode corresponding to the digital front-end module. For example, a mapping relationship between a preset data rate and a receiving manner may be preset, and then, a target receiving manner corresponding to a target data rate may be determined based on the mapping relationship, and then, a preamble signal and a data signal may be received according to the target receiving manner.

Optionally, in step 502, determining a target receiving manner corresponding to the target data rate, and receiving the preamble signal and the data signal according to the target receiving manner, may be implemented as follows:

when the target data rate is greater than a preset data rate, receiving the preamble signal by adopting a low intermediate frequency receiving mode, and receiving the data signal by adopting a zero intermediate frequency receiving mode;

and/or the presence of a gas in the gas,

and when the target data rate is less than or equal to the preset data rate, receiving the preamble signal and the data signal by adopting the low intermediate frequency receiving mode.

In this embodiment of the present application, the preset data rate may be preset or default to the system. The frequency offset is a difference value between a frequency point of the data signal and a frequency point of the preamble signal.

In the embodiment of the present application, when the target data rate is greater than the preset data rate, the signal format may be regarded as a high-rate signal format, whereas when the target data rate is less than or equal to the preset data rate, the signal format may be regarded as a low-rate signal format, or may also be regarded as a non-high-rate signal format.

In the high-rate signal format, the frequency offset is not 0, the signal bandwidth of the data signal is greater than that of the preamble signal, and the frequency point of the data signal is different from that of the preamble signal; the frequency offset of the low-rate signal format is 0, the signal bandwidth of the data signal is equal to that of the preamble signal, and the frequency point of the data signal is equal to that of the preamble signal.

In a specific implementation, when the target data rate is greater than the preset data rate, the preamble signal may be received by using a low intermediate frequency receiving manner, and the data signal may be received by using a zero intermediate frequency receiving manner, where in the low intermediate frequency receiving manner, the DFE needs to perform digital down-conversion, and in the zero intermediate frequency receiving manner, the DFE does not need to perform digital down-conversion.

In specific implementation, for a non-high-rate signal format (for example, a conventional bluetooth format or a BLE format), in the embodiment of the present application, a low-intermediate frequency scheme may still be maintained, and since frequency points of a data signal and a preamble signal sent by a transmitting end do not shift, that is, a frequency shift is 0, a receiving end receives in a low-intermediate frequency manner, and at this time, the receiving end is not affected by dc offset.

In the embodiment of the application, compare in low intermediate frequency scheme, because use zero intermediate frequency to receive data signal, consequently, can reduce the size of simulation low pass filter passband, so not only simplified the design, can filter more out-of-band noise and interference simultaneously, guarantee the receptivity.

In the embodiment of the application, the receiving performance is ensured for the signal format of low rate and the signal format of high rate, and when the signal format is directed to the bluetooth signal, the receiving scheme can be compatible with the low and intermediate frequency receiving schemes of original bluetooth BR and BLE, and meanwhile, the receiving of the bluetooth format of higher rate can be supported.

Optionally, the receiving the data signal in the zero intermediate frequency receiving manner in the above step may include the following steps:

a1, estimating a target direct current offset according to the preamble signal;

a2, determining a target compensation parameter corresponding to the target direct current offset;

and A3, receiving the data signal in the zero intermediate frequency receiving mode according to the target compensation parameter.

In the embodiment of the present application, due to zero-if reception, if the frequency offset is greater than 0, the data signal is affected by dc offset, and the dc value estimated by the preamble in the DFE needs to be used for compensation to ensure the reception performance.

In specific implementation, the preamble signal includes a signal header including demodulation information, the target dc offset is estimated by using the demodulation information, a mapping relationship between a preset dc offset and a compensation parameter may be pre-stored, the target compensation parameter corresponding to the target dc offset may be determined based on the mapping relationship, and finally, the data signal may be received by a zero intermediate frequency reception method according to the target compensation parameter, thereby reducing or eliminating the influence of the dc offset and ensuring the reception performance.

Optionally, in the step A1, estimating the target dc offset according to the preamble signal may include the following steps:

a11, acquiring a signal head of the preamble signal;

and A12, determining the target direct current offset according to the signal head.

In specific implementation, a signal head of a preamble signal can be extracted, and a target direct current offset is determined based on a signal corresponding to the signal head, so that a corresponding direct current offset can be accurately obtained, accurate compensation of a received signal is facilitated, and receiving performance is guaranteed.

Optionally, in the step a12, determining the target dc offset according to the signal header may include the following steps:

a121, acquiring a part of or all signal segments corresponding to the signal head;

a122, carrying out mean value operation on the partial or all signal sections to obtain a target mean value;

and A123, determining the target direct current offset according to the target mean value.

In the embodiment of the present application, a partial or all signal segments corresponding to a signal header may be obtained, for example, a synchronization point may be selected, that is, a frequency point that ensures synchronization between a preamble signal and a data signal is obtained, any one or more signal segments between the synchronization point and a guard interval are obtained based on the synchronization point, a partial or all signal segments corresponding to the signal header are obtained, an average operation is performed on the partial or all signal segments to obtain a target average value, that is, the partial or all signal segments may be summed and then the target average value is obtained, or energy values corresponding to the partial or all signal segments may be summed and then the average value is obtained, so as to obtain a corresponding target average value, and finally, a target dc offset corresponding to the target average value may be determined according to a mapping relationship between a pre-stored preset average value and the dc offset, so that the corresponding dc offset may be accurately obtained, which is helpful to implement accurate compensation of a received signal, and ensure reception performance.

Optionally, in the step A3, the data signal is received in the zero intermediate frequency receiving manner according to the target compensation parameter, and the following manner may be implemented:

compensating the data signal according to the target compensation parameter to obtain a compensated data signal, and receiving the compensated data signal by adopting the zero intermediate frequency receiving mode;

or,

and receiving the data signal by adopting the zero intermediate frequency receiving mode, and compensating the data signal according to the target compensation parameter to obtain a compensated data signal.

In this embodiment of the present application, the data signal may be compensated according to a target compensation parameter to obtain a compensated data signal, for example, the compensation parameter may be k, and for example, a value range of k may be 0 to 0.2, then the compensated data signal = (1 + k) = data signal, and the compensated data signal is received in a zero intermediate frequency receiving manner, that is, the data signal is compensated first and then received in a zero intermediate frequency receiving manner, so that an influence of a dc offset may be reduced or eliminated, and a receiving performance is ensured.

In this embodiment of the present application, a zero intermediate frequency receiving manner may be adopted to receive a data signal, and the data signal is compensated according to a target compensation parameter, so as to obtain a compensated data signal, for example, the compensation parameter may be k, for example, a value range of k may be 0 to 0.2, and then the compensated data signal = (1 ++ k) = the data signal, that is, the data signal is received in the zero intermediate frequency receiving manner and then compensated, so that an influence of a dc offset may be reduced or eliminated, and a receiving performance is ensured.

For example, taking a bluetooth signal as an example, in the embodiment of the present application, for a high-rate signal format (e.g., a non-legacy bluetooth format or a BLE format), the bluetooth signal is divided into the following two parts:

1) The preamble and the signal head (hereinafter collectively referred to as preamble signals) still keep 1MHz bandwidth and are modulated by GFSK;

2) The payload carrying the data (data signal) is transmitted with a high bandwidth (e.g., 2MHz, 4MHz, etc.) and higher order modulation (e.g., 8 PSK).

To illustrate, as shown in fig. 7, when the bluetooth signal is transmitted, the frequency point (denoted by f 1) of the preamble signal and the frequency point (denoted by f 2) of the data signal are shifted by 1MHz, that is, f1-f2=1MHz. When the receiver is receiving, the low intermediate frequency reception mode (DFE needs digital down-conversion) of IF =1MHz is still used for the preamble signal, and correspondingly, the zero intermediate frequency (IF = 0) reception mode (DFE does not need digital down-conversion) is performed for the data signal, as shown in fig. 7 a.

Further, for signal formats other than high rate (e.g., legacy bluetooth format or BLE format), the low-if scheme is still maintained: the frequency points of the data signal and the preamble signal transmitted by the transmitting end have no offset, and the receiving end receives the data signal and the preamble signal in a low-intermediate frequency manner, as shown in a diagram b in fig. 7.

In summary, in the embodiments of the present application, on one hand, for a data signal with a large bandwidth, the center frequency points of the preamble signal and the data signal are innovatively shifted (for example, 1 MHz), so that the receiving device can receive the preamble signal using a low intermediate frequency, and simultaneously receive the data signal using a zero intermediate frequency, thereby effectively reducing the passband range of the analog low-pass filter, and at the same time, being well compatible with low intermediate frequency reception in the classic bluetooth BR format and the BLE format; on the other hand, the leading signal is received through the low intermediate frequency, so that the leading signal is not influenced by the direct current offset, the direct current offset can be conveniently counted, and the zero intermediate frequency receiving of the data signal cannot be influenced by the direct current offset through the direct current compensation, so that the receiving performance of the Bluetooth signal under the dynamic data rate is ensured.

It can be seen that the signal transmission control method described in the embodiment of the present application is applied to a receiving device, determines a target data rate of a signal format of a signal sent by a sending device, where the signal includes a preamble signal and a data signal, determines a target receiving mode corresponding to the target data rate, and receives the preamble signal and the data signal according to the target receiving mode, where the target receiving mode is a receiving mode corresponding to a digital front-end module, and thus, the receiving mode of the corresponding digital front-end module is selected based on the data rate corresponding to the signal format of the signal, and the receiving performance of the signal can be ensured for different data rates.

In accordance with the above, please refer to fig. 8, fig. 8 is a schematic flowchart of another signal transmission control method provided in this embodiment of the present application, and is applied to a sending device, where the sending device is shown in fig. 1 or fig. 2, and as shown in the diagram, the signal transmission control method includes:

801. a target data rate for a signal format between the sending device and a receiving device is determined.

In this embodiment, for example, a sending device and a receiving device may communicate with each other, and the sending device may send a signal to the receiving device, where the signal may include a preamble signal and a data signal, where the data signal may carry signal content, and the preamble signal is a signal for performing time synchronization between the sending device and the receiving device.

In specific implementation, different signals correspond to different signal formats, different signal formats correspond to different data rates, and the data rate of a signal can be determined according to the signal format of the signal.

802. And sending signals to the receiving equipment according to the target data rate, wherein the signals comprise a preamble signal and a data signal, determining a target receiving mode corresponding to the target data rate through the sending equipment, and receiving the preamble signal and the data signal according to the target receiving mode, wherein the target receiving mode is a receiving mode corresponding to a digital front-end module.

In the embodiment of the present application, different receiving modes are set for different data rates, where the receiving mode is a receiving mode corresponding to the digital front end module. For example, a mapping relationship between a preset data rate and a receiving manner may be preset, and then, a target receiving manner corresponding to a target data rate may be determined based on the mapping relationship, and then, a preamble signal and a data signal may be received according to the target receiving manner.

Optionally, the method may further include the following steps:

b1, determining a target channel quality evaluation value between the sending equipment and the receiving equipment;

and B2, determining the target data rate according to the target channel quality evaluation value.

In a specific implementation, channel quality evaluation may be performed on a communication channel between a sending device and a receiving device, specifically, at least one channel quality evaluation index may be used to perform channel quality evaluation on the communication channel to obtain at least one evaluation result, where each channel quality evaluation index corresponds to one evaluation result, and then a weighting operation is performed on the evaluation results to obtain a target channel quality evaluation value, where the channel quality evaluation index may include at least one of: the Received Signal Strength Indication (RSSI), the packet loss rate, the bit error rate, the drop rate, and the like are not limited herein, but, of course, a preset mapping relationship between the channel quality evaluation value and the data rate may be preset, and the target data rate corresponding to the target channel quality evaluation value may be determined based on the mapping relationship, and since different data rates correspond to different bandwidths, the bandwidth of the data signal may be dynamically adjusted based on the current channel condition, for example, the current channel condition may be determined by using multiple indexes such as the retransmission or the RSSI, and then, a corresponding receiving manner may be selected based on different data rates to ensure the receiving performance.

In the embodiment of the application, flexible adaptive rate transmission can be supported, and the transmitting device can dynamically adjust the data rate of the current signal according to the actual situation, so that the transmission rate is ensured, and the receiving device can also correctly receive the signal.

Optionally, the method may further include the following steps:

determining the highest and widest between the sending equipment and the receiving equipment through a negotiation mode; and the signal bandwidth of the data signal corresponding to the target data rate is less than or equal to the highest bandwidth.

In a specific implementation, the highest and the widest between the sending device and the receiving device may be determined in a negotiation manner, that is, no matter how the sending device and the receiving device dynamically adjust the signal bandwidth of the data signal, the highest bandwidth should not be exceeded by the sending device and the receiving device.

It can be seen that the signal transmission control method described in the embodiment of the present application is applied to a sending device, determines a target data rate of a signal format of a signal between the sending device and a receiving device, sends a signal to the receiving device according to the target data rate, where the signal includes a preamble signal and a data signal, determines a target receiving mode corresponding to the target data rate through the sending device, and receives the preamble signal and the data signal according to the target receiving mode, where the target receiving mode is a receiving mode corresponding to a digital front-end module, and thus, a receiving mode of the corresponding digital front-end module is selected based on the data rate corresponding to the signal format of the signal, and the receiving performance of the signal can be ensured for different data rates.

In accordance with the above, please refer to fig. 9, fig. 9 is a schematic flow chart of another signal transmission control method according to an embodiment of the present application, and as shown in the figure, the signal transmission control method includes:

901. a transmitting device determines a target data rate for a signal format of a signal between the transmitting device and a receiving device.

902. And the sending equipment sends the signals to the receiving equipment according to the target data rate, wherein the signals comprise preamble signals and data signals.

903. The receiving device determines the target data rate for a signal format of a signal transmitted by the transmitting device.

904. And the receiving equipment determines a target receiving mode corresponding to the target data rate, and receives the preamble signal and the data signal according to the target receiving mode, wherein the target receiving mode is a receiving mode corresponding to a digital front-end module.

The specific description of the above steps 901 to 904 may refer to the related description of the signal transmission control method described in fig. 5 or fig. 8, and is not repeated herein.

For example, in a real-world scenario, the channel environment is complex and changeable, and the RSSI of a signal at the last time is likely to be high, but since the RSSI of a signal at the next time suddenly drops due to the movement of a user or a change in the manner of wearing a device, it is necessary to perform variable-rate data transmission according to actual situations. Based on the above two signal format receiving modes, the embodiment of the present application can well support the transmission scheme of the adaptive data rate.

For example, taking a bluetooth signal as an example, as shown in fig. 10, in the process of transmitting the bluetooth signal, the method may include the following steps:

s1, a transmitting and receiving end negotiates the highest bandwidth;

s2, the sending end selects the corresponding data signal bandwidth according to the channel condition;

s3, the receiving end receives the signal head signal through the low intermediate frequency and estimates a direct current value;

s4, whether the data signal bandwidth is 1MHz?

S5, if yes, configuring the DFE to receive signals at a low intermediate frequency;

and S6, if not, configuring the DFE to receive the data signal at zero intermediate frequency and compensating the direct current value.

Specifically, when the preamble of the bluetooth signal is 1MHz bandwidth, and when the transmitting and receiving ends negotiate the transmission bandwidth (for example, the highest bandwidth is 4 MHz), the transmitting device may dynamically adjust the signal bandwidth (for example, 4MHz,2mhz, and 1mhz) of the data signal according to the current channel condition (for example, determined by multiple indicators such as retransmission or RSSI), the receiving device performs low-intermediate frequency reception of the preamble at the negotiated frequency point and estimates the dc offset, and after demodulating the signal header therein, determines the bandwidth type of the current data signal, the DFE is configured to perform data reception, specifically: if the bandwidth of the data signal is 1MHz, the low intermediate frequency is still used for receiving, and if the bandwidth of the data signal is greater than 1MHz, the DFE is configured to receive data through the zero intermediate frequency, because of zero intermediate frequency reception, at this time, the data signal is affected by the dc offset, and the dc value (i.e., the dc offset) estimated by the preamble needs to be used in the DFE for compensation.

In the embodiment of the application, because the zero intermediate frequency is used for receiving the data signal, the size of the passband of the analog low-pass filter can be reduced, so that the design is simplified, more out-of-band noises and interference can be filtered, and the receiving performance is ensured. In addition, the receiving performance is ensured not only for the signal format with low rate but also for the signal format with high rate, the low and intermediate frequency receiving schemes of the original Bluetooth BR and BLE can be compatible, and meanwhile, the receiving of the Bluetooth format with higher rate can be supported.
