Another objective of the present invention is to provide a wireless communication method for an intelligent nursing machine, which combines the MIMO technology with the MIMO technology, and separates multiple signals from the entropy domain by using the entropy division multiplexing algorithm, including transmitting n source signals, receiving aliasing signals at the receiving end, and separating the aliasing signals by the separation system;

the transmitting of the n source signals means that the n source signals are mixed through channels, a mixing system is called A, and the n source signals are transmitted in space by n antennas at a transmitting end;

the receiving end receives the aliasing signals, namely the receiving end receives the aliasing signals by using m (m is more than or equal to n and is more than 1) antennas, the received signals are called observation signals, the receiving end firstly carries out pretreatment on the observation signals, and the pretreatment comprises two parts, namely centralization treatment and sphericization treatment;

the separation system for the multi-channel aliasing signals means that the separation system W can separate the multi-channel aliasing signals in an entropy domain according to different information entropy values of all the channels of source signals, wherein the criterion of the information entropy values adopts negative entropy;

wherein, the expression of the negative entropy approximate calculation is as follows:

$\hat{J}\left(x\right)\≈\underset{j=1}{\overset{n}{\Σ}}{k}_j{\[E\left\{G_j\left(x\right)\right\}-E\left\{G_j\left(M\right)\right\}\]}^2$ (formula 1)

Wherein k is_jM is a Gaussian variable with zero mean, unit variance, and function G is some normal number_jIs a non-quadratic function;

when all G are_jWhen G, the approximate formula is:

J_G(x)≈C[E{G(x)}-E{G(M)}]²(formula 2)

Wherein G is an arbitrary non-quadratic function, and C is a constant;

then, the above formula is adopted to calculate the negative entropy, and each path of signal is extracted according to the difference of the negative entropy value of each path of signal, so that the multiplexing of the channel is realized.

Further, the separation system separates multiple alias signals due to the Multiple Input Multiple Output (MIMO) technology that adopts multiple antenna transmission and multiple antenna reception, the limit channel capacity of the MIMO-EDM wireless communication system increases linearly with the increase of the number of transmit and receive antennas, and the calculation process of the limit capacity of the MIMO-EDM wireless communication system is as follows:

calculated using Laguerre polynomial:

$C={\∫}_0^{\mathrm{\∞}}{\log }_2(1+\frac{1}{n_t}\mathrm{\ξ}\mathrm{\λ}\underset{k=0}{\overset{m-1}{\Σ}}\frac{k!}{(k+n+m)!}{\[L_k^{n-m}\left(\mathrm{\λ}\right)\]}^2{\mathrm{\λ}}^{n-m}{e}^{-\mathrm{\λ}}d\mathrm{\λ})$ (formula 3)

Wherein m is min (N)_t，N_r)

n＝max(N_t，N_r)

Of order kLaguerre polynomial:

if let λ = n/m, deriving the normalized channel capacity expression as follows;

$\underset{n\→\mathrm{\∞}}{\lim }\frac{C}{m}=\frac{1}{2\mathrm{\π}}{\∫}_{v_1}^{v_2}{\log }_2(1+\frac{m\mathrm{\ξ}}{N_t}v)\sqrt{(\frac{v_2}{v}-1(1-\frac{v_1}{v})}dv$ (formula 4)

Wherein, $v_1={(\sqrt{\mathrm{\τ}}-1)}^2$

$v_2={(\sqrt{\mathrm{\τ}}+1)}^2$

in the case of fast rayleigh fading, let m-N_t＝N_rThen v is₁＝0，v₂＝4；

The progressive channel capacity is:

$\underset{n\→\mathrm{\∞}}{\lim }\frac{C}{n}=\frac{1}{\mathrm{\π}}{\∫}_0^4{\log }_2(1+\mathrm{\ξ}v)\sqrt{(\frac{1}{v}-\frac{1}{4})}dv$ (formula 5)

Using the inequality:

log₂(1+x)≥log₂(x) (formula 6)

Equation (5) reduces to:

$\underset{n\→\mathrm{\∞}}{\lim }\frac{C}{n}=\frac{1}{\mathrm{\π}}{\∫}_0^4{\log }_2\left(\mathrm{\ξ}v\right)\sqrt{(\frac{1}{v}-\frac{1}{4})}dv\≥{\log }_2\left(\mathrm{\ξ}\right)-1$ (formula 7)

Equation (5) shows that the capacity of the limit channel increases linearly as the number of transmit and receive antennas increases.

The invention has the advantages and positive effects that: the intelligent nursing machine can be widely applied to the technical field of medical instruments, and meanwhile, the laser device and the intelligent nursing device are arranged, the intelligent nursing machine is designed in a modularized mode, can be assembled according to use functions, the weight and the volume of a nursing instrument are reduced as much as possible under the condition that actual use requirements are met, the sensor module is connected with the microprocessor through the signal input interface, meanwhile, the GPS positioning device and the wireless transmitting module which are integrated inside the sensor module can position the specific position of a patient and transmit signals back to the microprocessor, so that the patient can move freely under the condition that monitoring is not influenced, the intelligent nursing machine is convenient to operate, accurate, reliable, safe and practical, the working efficiency is improved, the functional diversity is improved, the manufacturing cost is further reduced, and the intelligent degree is improved. The wireless communication module can separate multiple signals from an entropy domain by using an entropy division multiplexing algorithm (entropy division multiplexing EDM), realizes multiplexing of channels, has larger channel capacity and higher spectrum utilization efficiency, and can realize high-speed and high-quality broadband wireless communication; the MIMO-EDM wireless communication method overcomes the defect that channel resources can only be fixedly distributed in the traditional orthogonal frequency division multiplexing mode, solves the problems of mutual interference and multi-access interference of all paths of signals in time domain and frequency domain during signal transmission, and realizes multiplexing of time-frequency aliasing multi-path aliasing signals in an information entropy domain.
