It should be noted that Wireless energy Transfer technology (SWIPT) is a novel Wireless communication type, and is different from the traditional Wireless communication that only transmits Information, and the Wireless energy Transfer technology can also provide energy to the Wireless terminal while transmitting Information, and the technology converts a part of received signals into energy, and the Wireless energy can be stored in the battery of the Wireless terminal through a series of conversion, and the captured energy will be used for energy consumption of the normal Information interaction circuit and energy consumption of the energy capture circuit of the Wireless terminal. Therefore, the method replaces the inconvenience brought by the traditional wired or battery power supply, reduces the volume and the cost of the terminal, and is particularly suitable for the application of terminal nodes needing large-scale distribution.
However, when the existing wireless energy-carrying transmission is performed, there is a certain probability that the energy shortage phenomenon occurs, that is, the transmission power of the source node is reduced, and noise interference in the transmission process is added, so that the energy received by the relay node is insufficient to decode the received message, and finally, the technical problem that the error rate of the message received by the target node is high is caused.
In order to make the objects, features and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the embodiments described below are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

And 103, judging that the first test energy is greater than the second test energy and greater than a preset decoding energy consumption threshold, if so, executing a step 104.
It should be noted that, it is determined whether the first test energy is greater than the second test energy and greater than the preset decoding energy consumption threshold, and it is determined whether the source node is suitable for transmitting data in the current transmission environmentThe relay node transmitting information, i.e. PSR,E≥ρPRD,EIn the formula, PSR,EIs a first test energy, PRD,EFor the second test energy, ρ represents a threshold constant for link selection.
It should be noted that, in step 101, the obtained received energy is compared with a preset decoding energy consumption threshold, and whether the energy value of the received energy is greater than the preset decoding energy consumption threshold is determined, where the decoding energy consumption threshold of this embodiment may be measured through a limited number of decoding energy consumption tests, and the final decoding energy consumption threshold may be an average value of test results of each time, or a corresponding decoding energy consumption test result may be set as the decoding energy consumption threshold according to different received information signals, which is not described herein again.
And step 104, receiving the modulation signal sent by the source node.
It should be noted that, as long as the received energy is greater than the decoding energy consumption threshold, it indicates that the received energy value in the transmission process of this time is sufficient, and the probability of the energy shortage phenomenon occurring when the source node sends a signal is small, at this time, the modulation signal sent by the source node may be received, so that the received energy and the information signal are continuously stored in the energy buffer region and the information buffer region, respectively, and the information signal is decoded and sent to the target node.
According to the embodiment of the application, energy shortage judgment is added into the relay node for wireless transmission, firstly, according to different buffer area states, energy collected by two transmission links is compared with a preset decoding energy consumption threshold, and if the energy collected from a source node is larger than the energy collected from a destination node and is larger than the preset decoding energy consumption threshold, signals are normally transmitted; otherwise, the information transmission is interrupted. Based on the protocol, the signal with higher transmission failure risk can be effectively intercepted, the error code receiving quantity of the system destination node is controlled, and the technical problem that the transmission error rate of the existing wireless energy-carrying communication system is high is solved.
The above is a detailed description of a first embodiment of a relay transmission control method based on wireless energy carrying provided by the present application, and the following is a detailed description of a second embodiment of the relay transmission control method based on wireless energy carrying provided by the present application.
Referring to fig. 2, 4, 5 and 6, a second embodiment of the present application provides a relay transmission control method based on wireless energy carrying, including:
It should be noted that, when implementing the embodiments of the present application, first, it is determined whether the information buffer is in a non-full state to determine whether the relay node has a space for receiving new information, and if so, the source node and the destination node respectively send a first test signal and a second test signal to the relay node.
It should be noted that, it is determined whether the first test energy is greater than the second test energy and greater than the preset decoding energy consumption threshold, and it is determined whether the source node is suitable for sending information to the relay node in the current transmission environment, that is, PSR,E≥ρPRD,EIn the formula, PSR,EIs a first test energy, PRD,EFor the second test energy, ρ represents a threshold constant for link selection. It should be noted that, in the following description,
and step 204, receiving the modulation signal sent by the source node.
It should be noted that, as long as the received energy is greater than the decoding energy consumption threshold, it indicates that the received energy value in the transmission process of this time is sufficient, and the probability of the energy shortage phenomenon occurring when the source node sends a signal is small, at this time, step 204 may be executed to receive the modulated signal sent by the source node, so as to continue steps such as step 205, and the like, so as to store the received energy and the information signal in the energy buffer area and the information buffer area, decode the information signal, and send the decoded information signal to the target node.
It should be noted that, if the received energy is smaller than the decoding energy consumption threshold, it indicates that the energy value received in the transmission process of this time is small, the energy shortage phenomenon occurs at a high probability when the source node sends a signal, and it is difficult to ensure the accuracy of transmission to continue transmission, at this time, the step 204 is not executed, and the transmission process of this time is interrupted.
It should be noted that, for transmission of S- > R link, the DCSK modulated signal transmitted at the kth with spreading factor β is written as
Where x (n) represents a DCSK modulated signal transmitted by the source node. Similarly, the received signal of the relay node can be written as:
wherein, PSRepresenting constant transmission power of the source node, dmnWhere mn ∈ { sr, rd } is the distance between two nodes m and n, and α is the path fading coefficient. In addition, the first and second substrates are,

is defined as S->Time delay of R link, nsr(t)～(0,N0/2) is additive white Gaussian noise. The signal received at the relay is split into two parts, one part being converted into collected energy and the other part being stored in the IR receiver waiting for signal transmission. After determining that the collected power is sufficient to decode the received signal, the collected power and part of the signal are temporarily stored in their corresponding power buffer EH and information buffer IR, respectively.
After power splitting, the signal received at the information buffer IR can be written as
Wherein the power distribution ratio is represented by e, and the value range is 0<e<1。
Representing the chaotic signal sent by the source node. Due to conversion of the radio frequency signal into a baseband signal, nIR(t)～(0,NIR/2) is complex white Gaussian noise. The power signal available at the energy buffer is
κ represents an energy conversion efficiency factor.
And step 207, acquiring the first test energy and the second test energy in real time.
It should be noted that, the manner of obtaining the first test energy and the second test energy in step 207 may refer to the manner of step 202, which is not described herein again.
And step 209, decoding the information signal stored in the information buffer area by using the received energy stored in the energy buffer area to obtain a decoded information signal.
And step 210, sending the decoded information signal to a target node by using the residual energy obtained by decoding the received energy.
It should be noted that, similarly, when the modulation signal is sent to the destination node, it may also be determined whether a transmission link state from the current relay node to the destination node is suitable for transmitting the signal, and when it is determined that the second test energy is greater than the first test energy, decoding of the information signal may be started, so as to perform the next transmission.
For R- > D link transmission, the relay node is used to transmit the re-modulated signal. Thus, the remodulated signal received by the target node D can be written as:
wherein the content of the first and second substances,
representing the chaotic signal received by the target node. In order to correctly decode the received signal, a part of the energy P is consumedcoResidual energy PRFor completing the transmission of information, known as PR＝PSR,E-Pco. Furthermore, it is possible to provide a liquid crystal display device,

PSR,EAnd PRD,ERespectively represent S->R and R->D energy collected by link. N is a radical ofiRepresenting the size of the data amount in the i-slot buffer, and J representing the size of the buffer.
More specifically, the relationship between the energy state and the change of the buffer area in this embodiment is shown in table 1:
TABLE 1 energy State versus buffer Change
Where X means that the energy shortage is independent of link selection and J is the upper storage limit of the buffers (energy buffer and information buffer).
As shown in table 1, the source node S to the destination node D will be discussed from four different conditional probabilities as follows:
1) when the buffer state is empty, only when the energy collected by the first link is larger than the energy collected by the second link and the decoding energy consumption threshold value, namely PSR,E≥ρPRD,E&PSR,E＞PcoSelecting from S->The R link is used for transmission, and an information symbol is added to the buffer area state at the relay node; at this time, if a problem of energy shortage occurs, transmission from the source node S to the relay node may be interrupted.
2) When the buffer status is full, only P is neededSR,E＜ρPRD,EWhen the signal is directly sent from the relay node R to the target node D, one information symbol is reduced in the buffer area.
3) If P is not empty or full in the buffer statusSR,E≥ρPRD,E&PSR,E＞PcoWhen it is, S->The R link is successfully transmitted, and the state of the buffer area is increased by one bit; but if the energy collected by the first link is not sufficient to recover the received signal, S->The transmission of the R link is interrupted, and the state of the buffer area is unchanged.
4) If the buffer status is not empty or full, if PSR,E＜ρPRD,EWhen it is, R->And D, link transmission, and the buffer area state is reduced by one bit.
Referring to fig. 5 and fig. 6, the following are inspection results obtained after simulation based on the relay transmission control method, and specifically include:
as shown in fig. 5, based on this exampleThe error rate performance of the relay transmission control method provided by the embodiment is compared with that of several traditional DCSK system transmission methods. By considering single path and non-uniformly distributed multipath Rayleigh channels, Lsr＝Lrd3 and S->R link and R->Distance between D links is Dsr＝drdThe size of the buffer is set to be finite, 1. Let parameter ρ be 1.05 and energy conversion efficiency κ be 0.6. As shown in the figure, the bit error rate performance of the link selection protocol proposed by the patent is about 6dB better than that of the traditional point-to-point DCSK system in both single path and multipath. At high signal-to-noise ratio, the system proposed herein is about 2dB better than the two-hop relay model of S-R-D without buffer.
As shown in fig. 6, the variation between buffer size and average delay at different parameter values ρ. As can be seen, the average delay increases linearly with increasing buffer size, giving a parameter theta of 0.55. For ρ 0.95, the average delay is much larger than that for ρ 1.05, because when ρ 0.95, in most cases, S- > R link can be selected for transmission, which results in more and more data in the buffer, and thus larger queue delay. And the best case is when rho is 1.05, compared with the error rate performance of the traditional DCSK system, the error rate performance of the system is obviously improved, and meanwhile, the time delay is better. How to balance the bit error rate and the time delay problem needs to be decided by different practical application scenarios.
According to the embodiment of the application, energy shortage judgment is added into a relay node for wireless transmission, firstly, according to different buffer area states, energy collected by two transmission links is compared with a preset decoding energy consumption threshold, and if the energy collected by a first transmission link is simultaneously larger than the energy collected by a second transmission link and the decoding energy consumption threshold, signals are transmitted normally; otherwise, if the collected energy is smaller than the decoding energy consumption threshold, the information transmission is interrupted. Based on the protocol, the error rate performance of the system is effectively improved, and the technical problem that the transmission error rate of the existing wireless energy-carrying communication system is high is solved.
