摘要

在包含中继节点的D2D（Device-to-Device）系统中，针对蜂窝链路与D2D链路同时受窃听的问题，提出一种基于链路间干扰辅助的中继D2D系统安全通信方法.首先，确定蜂窝链路与D2D链路上下行发送模式；然后，在基站与中继节点的发送信号中添加人工噪声，协作干扰窃听者；最后，对基站功率分配与D2D功率控制进行了优化，以实现不同类型链路间干扰辅助保障系统安全.仿真结果表明，所提出的安全通信方法在保密速率方面比SVD（Singular Value Decomposition）与ZF（Zero-Forcing）预编码方法提高了1.5bit/s/Hz.

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.
