摘　　要：为满足智能信号处理和物理层安全需求,针对频谱资源紧缺问题,提出了一种智能超表面辅助设备到设备(D2D)通信的资源分配算法。D2D用户通过复用蜂窝用户频谱资源实现通信,考虑D2D传输速率、基站发射功率和RIS发射相移约束,构建了用户保密速率最大化问题。为了解决该非线性规划问题,提出了一种并行卷积神经网络算法,以得到最佳资源分配方案。仿真结果表明,所提算法能够有效提高系统保密速率,且明显优于其他基准算法。To meet the requirements of intelligent signal processing and physical layer security,aiming at the shortage of spectrum resources,a resource allocation algorithm for reconfigurable intelligent surface(RIS)-assisted the device to de-vice(D2D)communication was proposed.D2D users communicated by multiplexing the spectrum resources of cellular users.Considering the constraints of D2D transmission rate,base station transmission power and RIS transmission phase shift,the problem of maximizing user security rate was formulated.To solve the nonlinear programming problem,a pa-rallel convolutional neural network(CNN)algorithm was proposed to obtain the optimal resource allocation scheme.Si-mulation results show that the parallel CNN algorithm can effectively improve the secrecy rate and it is significantly bet-ter than other benchmark algorithms.
