And the total bandwidth of the architecture is set to ,in For ground communications and perception, Used for satellite-to-earth communications.
[0038] In the satellite-ground integrated power distribution network architecture, the first interactive signal data extracted from the corresponding link of the communication terminal includes all signals received by the downlink communication terminal, all signals sent by the uplink communication terminal to the base station, and all signals sent by the satellite direct connection terminal received by the satellite. The second interactive signal data extracted from the corresponding link of the computing terminal includes all signals sent by the computing terminal to the base station. The third interactive signal data extracted from the corresponding link of the perception terminal includes all echo detection signals sent by the perception terminal to the base station.
[0039] Based on this, in this embodiment, the interactive signal data extracted from the corresponding links of various terminals are modeled to obtain the uplink communication model, downlink communication model, satellite direct communication model, perception model and computing task offloading model. It can be understood that in this embodiment, Prior to this, the first choice is to model the transmission signals of all transmitting nodes in the network architecture. It is known that the signals sent by ground base stations consist of two parts: one is the integrated signal, which includes the signals of all downlink communication terminals and target perception signals; the other is the signal sent to the satellite.
[0040] In this embodiment, the synaesthesia integrated signal is expressed by the following formula: In the formula, It is sent by the base station to the downlink communication terminal. signal, satisfying , represents the expectation operation, Represents modulo operation; It is allocated by the base station to the downlink communication terminal. The beamforming vector of represents the complex domain, is the perception signal, and its covariance matrix is , represents the conjugate transpose.
[0041] The signal sent to the satellite is expressed as , the beamforming vector used is .
[0042] Uplink communication terminal The signal sent is represented by ,satisfy , the transmission power is .
[0043] The signal sent by the computing terminal is expressed as ,satisfy , the transmission power is .
[0044] The signal sent by the satellite direct connection terminal is expressed as ,satisfy , the transmission power is .
[0045] After modeling all the transmitted signals, the embodiment of the present invention will calculate the communication signal-to-noise ratio and data transmission rate corresponding to each terminal according to the modeling results. A specific example is provided below to describe the above process in detail: (1) Downlink communication model Set the base station to the downlink communication terminal The channel is , Uplink communication terminal To the downlink communication terminal The channel is , computing terminal To the downlink communication terminal The channel is , then the downlink communication terminal The first mixed signal received is sent by the base station to the downlink communication terminal The sum of the six parts is the signal sent by the base station, the accumulated signal sent by the base station to other downlink communication terminals, the perception signal sent by the base station, the signal sent by the uplink communication terminal, the signal sent by the computing terminal, and the noise.
[0046] The first mixed signal It is expressed as: In the formula, is the Gaussian white noise of the downlink communication terminal, The mean is 0 and the variance is The complex Gaussian distribution of .
[0047] Extracting the downlink communication terminal from the first mixed signal The received target signal power and interference signal power are calculated, and the ratio of the target signal power to the sum of multiple interference signal powers is obtained to obtain the downlink communication terminal Communication signal-to-interference-to-noise ratio , expressed by the following formula: It can be seen that the interference signal includes the accumulated signal sent by the base station to other downlink communication terminals, the perception signal sent by the base station, the signal sent by the uplink communication terminal, the signal sent by the computing terminal and the noise.
[0048] The obtained downlink communication terminal Communication signal-to-interference-to-noise ratio Substitute into the preset rate calculation formula, preferably, in this embodiment, substitute into the Shannon formula to calculate the data transmission rate of the downlink communication terminal , expressed as: (2) Perception Model After the sensing signal emitted by the base station reaches multiple targets, the reflected echo reaches the base station, and the base station then detects the target based on the echo. The direction angle of the target relative to the base station is , then the base station is The launch steering vector on and receive steering vector Respectively expressed as: The echo detection signal received at the base station It is expressed as: in, represents the complex channel coefficient.
[0049] Assume that the channels from the uplink communication terminal and the computing terminal to the base station are expressed as , Since the second mixed signal received at the base station includes the signal sent by the uplink communication terminal, the signal sent by the computing terminal, the echo detection signal and the noise, the second mixed signal It is expressed as: in, is the Gaussian white noise vector at the base station receiving array, is the covariance matrix.
[0050] Extract the first The target signal power and interference signal power of each target are calculated, and the communication signal-to-interference-noise ratio is obtained by calculating the ratio of the target signal power to the sum of multiple interference signal powers. , expressed by the following formula: In the formula, , All are From the receiving beamforming vector of the target echo signal, it can be seen that the interference signal includes the signal from the uplink communication terminal, the signal from the computing terminal, the echo detection signal of other targets and noise.
[0051] (3) Satellite direct communication model Since satellite-to-ground communication is not in the same frequency band as ground communication, satellite-to-ground communication is basically not interfered by ground signals. The signals received by the satellite only include the signals transmitted by the satellite direct connection terminal and the signals transmitted by the base station to the satellite. The channel to the satellite is , the channel from the base station to the satellite is , the third mixed signal received by the satellite is the sum of the satellite direct terminal signal, the base station to satellite signal and the noise. Then the third mixed signal It is expressed as: in, is the Gaussian white noise at the satellite receiver.
[0052] It is worth noting that in order to alleviate signal interference, in the embodiment of the present invention, satellite-to-ground communication adopts non-orthogonal multiple access (NOMA) technology, and the satellite receiver performs serial interference cancellation (SIC) to reduce interference between different signals. Specifically, assuming that the channel gains are ranked according to , and the satellite receiver decodes in descending order of channel gain, that is, the signal transmitted by the node with stronger channel gain is decoded first and removed from the received signal, and the remaining signal transmitted by the node with weaker channel gain is directly regarded as interference. Based on this, this embodiment calculates the terminal received by the satellite The ratio of the target signal power to the sum of the corresponding interference signal power is obtained by the terminal Communication signal-to-interference-to-noise ratio : According to Shannon's formula, the data transmission rate is: Similarly, calculate the signal-to-interference-to-noise ratio of the signal received by the satellite from the base station for: The data transfer rates are: (4) Uplink communication model According to the second mixed signal received by the base station The expression of the base station receiving the uplink communication terminal The ratio of the target signal power to the sum of multiple interference signal powers is obtained to obtain the uplink communication terminal The communication signal-to-interference-to-noise ratio is: in, It is From the receive beamforming vector of an uplink communication terminal, it can be seen that the interference signal includes the signals sent by other uplink communication terminals, the signal sent by the computing terminal, the echo detection signal and noise.
[0053] Therefore, according to Shannon's formula, the uplink communication terminal The data transfer rate is: (5) Computational task offloading model Set up terminal The computational tasks that need to be offloaded to the base station for processing are expressed as ,in Indicates the task data size, Indicates the number of CPU clock cycles required to calculate a unit of data. Indicates the maximum tolerable processing delay of the task. Computing resources are , represents the CPU frequency, in clock cycles / second. The processing time cost of offloading the task to the ground base station is calculated as: in, Indicates the transmission rate.
[0054] According to the second mixed signal received by the base station The expression of the base station receiving the data from the computing terminal The ratio of the target signal power to the sum of multiple interference signal powers is obtained by the terminal The communication signal-to-interference-to-noise ratio is: in, It is Calculate the receiving beamforming vector of the terminal.
[0055] The calculation terminal The data transfer rate is: According to the embodiments of the present invention, signal modeling is performed for uplink communication, downlink communication, perception target, satellite direct communication, and computing task offloading end respectively, and data transmission rate and signal-to-interference-and-noise ratio are derived to provide support for differentiated terminal needs and lay a solid foundation for the rational allocation of spectrum resources.
[0056] S2. Taking the maximum achievable total transmission rate of each communication terminal as the goal, a joint non-convex optimization function consisting of transmit beamforming, receive beamforming, transmit power, perception signal covariance matrix and synaesthesia optimization variables of computing resources is constructed according to the satellite-ground integrated power distribution network architecture; wherein the achievable total transmission rate is obtained by processing the transmission rate of each of the communication terminals.
[0057] In this embodiment, the resource allocation process will consider establishing a non-convex optimization problem, i.e., a non-convex optimization function, of the joint synaesthesia optimization variable, and convert it into a convex problem in the process of solving this non-convex problem. The convex optimization problem has a unique global optimal solution. After converting the non-convex problem into a convex form, it can ensure that the algorithm converges to the global optimal solution and avoids falling into the local optimal trap.
[0058] Based on this, in an embodiment of the present invention, according to the transmission rates of all uplink communications, downlink communications and satellite direct communication terminals calculated previously, with the maximum achievable total transmission rate of all these communication terminals as the goal, an objective function is established, that is, a joint non-convex optimization function combining multiple synaesthesia optimization variables is constructed, and the total transmission power constraint of the base station, the transmission power constraint of each communication terminal and each computing terminal, the perceived signal-to-interference-noise ratio constraint, the total amount of computing resources constraint, the task processing delay constraint, the receive beamforming power constraint and the return link rate constraint are used as constraints. Specifically, the embodiment of the present invention represents the transmit beamforming vector as: , , the receive beamforming vector is expressed as: , , , the transmission power is expressed as: , , , the covariance matrix of the perception signal is expressed as: , the computing resources allocated by the base station to the computing terminal are expressed as: .
[0059] Then the joint non-convex optimization function is constructed as: in is the set of variables optimized by synaesthesia. is the matrix trace operation, Indicates that the total transmit power of the base station is lower than the maximum power budget , , , They are the maximum transmission power limits for uplink communication terminals, computing terminals and satellite direct connection terminals, Indicates that the perceived signal-to-interference-to-noise ratio cannot be lower than the threshold , Indicates that the total computing resources allocated by the base station to each computing terminal does not exceed , Indicates that the delay of the computing task does not exceed , , , is the power normalization limit of the receive beamforming vector, Indicates that the return link rate between the base station and the satellite is between and between.
[0060] S3, decomposing the joint non-convex optimization function into two sub-functions and performing alternating iterative processing, formulating and executing a target synaesthesia computing resource allocation strategy according to the processing results.
[0061] In order to solve the constructed joint non-convex optimization function, the embodiment of the present invention decomposes it into two sub-function problems. By designing a non-convex objective function and a constraint condition convex approximation method, the two non-convex sub-function problems are transformed into a convex function problem that can be directly solved.
[0062] Specifically, the joint non-convex optimization function is decomposed into a first sub-function for optimizing transmit beamforming, transmit power and computing resources under the condition that the receive beamforming parameters are fixed, and a second sub-function for optimizing receive beamforming under the condition that the transmit beamforming, transmit power, perception signal covariance matrix and computing resource parameters are fixed. The first sub-function (SP1) is expressed as: It can be seen that is the transmit beamforming vector, transmit power and computing resource set corresponding to the first sub-function.
[0063] The second sub-function (SP2) is expressed as: It can be seen that, in the formula, It is the vector set of receive beamforming.
[0064] Furthermore, in the embodiment of the present invention, an alternating iterative algorithm is used in combination with a Gaussian randomization process to solve the first sub-function and the second sub-function.
[0065] The first is the solution process of the first sub-function (SP1). Since it is a non-convex optimization problem, the non-convex constraints corresponding to the first sub-function are converted into convex constraints by introducing auxiliary variables, and the semidefinite programming method combined with the Gaussian randomization process is used to solve the converted first sub-function.
[0066] Specifically, the transformed first sub-function (SP3) is expressed as: In order to eliminate the quadratic constraint, define , and satisfies , ,definition , and satisfies , , then constraint C1 can be rewritten as: Constraint C5 can be rewritten as: in, .constraint , , , Still non-convex constraints, we will perform convex approximation on them one by one, including the following steps: (1) Convex approximation of C7 Defining auxiliary variables , constraint C7 can be approximately transformed into the following constraint: in, Constraints C7.2, C7.4, and C7.5 are convex constraints, while C7.1 and C7.3 are non-convex constraints. To handle the non-convexity of C7.1, an auxiliary variable is introduced , converting C7.1 into: Introducing auxiliary variables , constraint C7.6 can be further transformed into: C7.8 is a convex constraint. C7.7 and C7.9 have the same form and can be written as a standard second-order cone convex constraint, expressed as: In order to deal with the non-convexity of C7.3, the arithmetic geometric mean (AGM) inequality is introduced, that is, ,in , if and only if According to the AGM inequality, C7.3 can be approximately transformed into the following convex constraint: In summary, the original constraint C7 is approximately converted to C7.2, C7.3', C7.4, C7.5, C7.7', C7.8, and C7.9'.
