针对D2D通信安全性受资源限制问题,提出一种基于人工噪声辅助的D2D异构蜂窝安全通信方法。首先建立系统可达保密速率模型,然后在基站的蜂窝通信信号中添加人工噪声,以最大化系统保密速率为目标设计蜂窝用户期望信号与人工噪声的波束矢量。同时,基于公平性约束提出一种基站功率分配、期望信号预编码向量以及D2D功率控制的联合优化算法。仿真结果表明,相比于传统的SVD预编码法和ZF方法,此方法下系统可达保密速率最高提升约2.7 bit·s

A secure communication scheme based on artificial noise assisted from base station(BS)was proposed to improve the system secrecy rate of the D2D underlaying cellular.Firstly
the system secrecy rate was modeled.Then the BS with multi-antennas added artificial noise(AN)in cellular user’s signal as well as designed beam vectors of the desired signal and artificial noise to maximize system secrecy rate.In the end
a joint optimization scheme based on the fairness constraint was introduced to optimize beam vectors of the desired signal
the power allocation for BS’s information signal and AN and the D2D power control.Simulation results show that the system ergodic secrecy rate can be improved 2.7 bit·s
