论文摘要
分析了无线通信链路通过大型反射表面（LRS）带有相误差的物理层安全性（PLS）。利用表达\ ac {lrs}基于等效标量褪色通道的\ ac {lrs}的结果的最新结果，我们表明evelopper的链接是Rayleigh的分布式，并且独立于合法链接。合法和窃听者的信噪比与反射元素的数量以及相当好的性能，即使在粗相量化的情况下，具有不同的缩放定律，也表明了LRS辅助通信的巨大潜力，以增强实用无线设置中的PLS。
The physical layer security (PLS) performance of a wireless communication link through a large reflecting surface (LRS) with phase errors is analyzed. Leveraging recent results that express the \ac{LRS}-based composite channel as an equivalent scalar fading channel, we show that the eavesdropper's link is Rayleigh distributed and independent of the legitimate link. The different scaling laws of the legitimate and eavesdroppers signal-to-noise ratios with the number of reflecting elements, and the reasonably good performance even in the case of coarse phase quantization, show the great potential of LRS-aided communications to enhance PLS in practical wireless set-ups.
