在多输入多输出（MIMO）无线通信中，空间调制（SM）最近已经成为一种新的传输方法。本文探讨了典型SM系统中的物理层安全性。我们提出了一个多天线的目的地和窃听接收机的保密率分析。针对未知位置的被动窃听者，研究了在不需要窃听者信道信息的情况下，通过信号和干扰联合传输的主动安全措施的有效性。我们证明了保密率和发射功率的折衷有源干扰提供的数字结果实现保密率和误码率（BER）在不同的接收机。
In multiple-input-multiple-output (MIMO) wireless communications, spatial modulation (SM) has recently emerged as a new transmission method. This letter explores the physical-layer security in typical SM systems. We present a secrecy rate analysis for multiple antenna destination and eavesdroppers receivers. Targeting against passive eavesdroppers in unknown locations, we study the efficacy of active security measure through joint signal and jamming transmission without the typical requirement of eavesdropper channel information. We demonstrate the secrecy rate and transmission power tradeoff in active source jamming by providing numerical results on achieved secrecy rate and the bit error rate (BER) at different receivers.
