基于链路间干扰辅助的中继D2D系统安全通信方法
Jamming Based Secure Relay-Aided D2D Transmission Method
摘要
Abstract
To cope with eavesdropping in both the cellular link and the D2D(Device-to-Device) link of relay-aided D2D system,this paper proposes a jamming based secure transmission method.Firstly,the transmission procedures of both the cellular link and the D2D link are modeled.Secondly,an artificial noise (AN) is added into the signal of the base station (BS) and the relay to interfere the eavesdropper.Finally,a joint optimization scheme for the power allocation of BS and the power control of D2D is introduced to maximize the system secrecy rate.Simulation results show that the system ergodic secrecy rate is increased by 1.5bit/s/Hz,which is great improvement compared with the scheme based on SVD and ZF.关键词
