摘要

安全是无线网络的一个重要问题。本文研究了异构海量MIMO系统中的安全传输问题。具有大规模天线的基站在无源多天线窃听器存在的情况下，通过低功率节点(lpn)向移动终端传输信号。研究了基于协同干扰中继的安全下行传输。同时我们采用了人工噪声来提高安全性。仿真结果表明，在具有干扰器和AN的异构大规模MIMO系统中，MT的信噪比高于Eve，所获得的正保密容量证明该方案可以保证传输的安全性。

Secure transmission based on cooperative jamming relay in heterogeneous massive MIMO system

Security is an important concern in wireless networks. In this paper, we study secure transmission in heterogeneous massive MIMO systems. Base station (BS) with large-scale antenna transmits signal to mobile terminals through low power nodes (LPNs) in the presence of passive multi-antenna eavesdroppers. We consider the secure downlink transmission based on cooperative jamming relay. Meanwhile we employ artificial noise to enhance the security. Our simulation results reveal in heterogeneous massive MIMO systems with Jammer and AN, the SNR of MT is higher than Eve, the obtained positive secrecy capacity prove this scheme can guarantee the secure transmission.
