摘要翻译：
本文研究了一种人工噪声辅助下的安全空间调制(SM)系统。为了在这样的系统中获得更高的保密率，提出了两种高性能的发射天线选择方案：基于泄漏和最大保密率（Max-SR）,并设计了一种广义欧几里得距离优化天线选择(EDAS)方法。从仿真结果和分析来看，四种TAS方案的SR性能由大到小依次为Max-SR、基于泄漏的EDAS、广义EDAS和随机（常规）。然而，所提出的Max-SR方法需要穷举搜索才能获得最优的SR性能，因此随着天线数目趋于中大规模，其复杂度极高。所提出的基于泄漏的方法以更低的复杂度逼近Max-SR方法。从而在复杂度和SR性能之间取得了良好的平衡。从误码率(BER)来看，它们的性能依次为：随机、基于泄漏、Max-SR和广义EDAS。

英文摘要：
  In this paper, a secure spatial modulation (SM) system with artificial noise (AN)-aided is investigated. To achieve higher secrecy rate (SR) in such a system, two high-performance schemes of transmit antenna selection (TAS), leakage-based and maximum secrecy rate (Max-SR), are proposed and a generalized Euclidean distance-optimized antenna selection (EDAS) method is designed. From simulation results and analysis, the four TAS schemes have an decreasing order: Max-SR, leakage-based, generalized EDAS, and random (conventional), in terms of SR performance. However, the proposed Max-SR method requires the exhaustive search to achieve the optimal SR performance, thus its complexity is extremely high as the number of antennas tends to medium and large scale. The proposed leakage-based method approaches the Max-SR method with much lower complexity. Thus, it achieves a good balance between complexity and SR performance. In terms of bit error rate (BER), their performances are in an increasing order: random, leakage-based, Max-SR, and generalized EDAS.
