论文摘要
本文研究了毫米波（MM-WAVE）通信的保密性能，并使用不完美的硬件和不确定的窃听位置。我们考虑使用掩盖光束形成的多个Antenna源与单人群目的地进行通信，以在存在被动窃听器（EVE）的情况下用人工噪声（AN）传输信息信号。对于此系统，我们在慢速下降的通道条件和硬件缺陷下，为秘密中断概率（SOP）（SOP）和秘密吞吐量提供了新的表达式。基于此，为信息而得出了最佳功率分配（OPA）解决方案，旨在最小化SOP并最大化保密吞吐量的信号。我们的结果表明，对于不完美硬件的一般情况，实现OPA解决方案是不平凡的。我们还强调，与最大比率传播和等功率分配的基准方案相比，我们提出的使用OPA方案提出的掩蔽束形式可显着增强保密吞吐量。
This paper examines the secrecy performance of millimeter-wave (mm-Wave) communications with imperfect hardware and uncertain eavesdropper location. We consider a multiple-antenna source communicating with a single-antenna destination using masked beamforming to transmit the information signals with artificial noise (AN) in the presence of a passive eavesdropper (Eve). For this system, we derive new expressions for the secrecy outage probability (SOP) and secrecy throughput with mm-Wave multipath propagation under slow-fading channel conditions and hardware imperfections. Based on this, optimal power allocation (OPA) solutions are derived for the information and AN signals aimed at minimizing the SOP and maximizing the secrecy throughput. Our results reveal that it is non-trivial to achieve an OPA solution for the general scenario of imperfect hardware. We also highlight that our proposed masked beamforming with OPA scheme significantly enhances the secrecy throughput compared with the benchmark schemes of maximal-ratio transmission and equal power allocation.
