论文摘要
在这封信中，我们分析了可重新配置的智能表面（RIS）辅助通信系统的保密性能，其空间无人驾驶飞机（UAVS）充当窃听器。我们考虑了基本站（BS）配备单个和多个天线的情况。合法用户的信噪比（SNR）和窃听者通过分析得出并通过计算有效的方法得出。千古秘密能力近似并以封闭形式的表达方式得出。结果验证了分析和近似表达式的准确性，并显示了RIS部署的安全增强效应。
In this letter, we analyze the secrecy performance of a reconfigurable intelligent surface (RIS)-aided communication system with spatially random unmanned aerial vehicles (UAVs) acting as eavesdroppers. We consider the scenarios where the base station (BS) is equipped with single and multiple antennas.The signal-to-noise ratios (SNRs) of the legitimate user and the eavesdroppers are derived analytically and approximated through a computationally effective method. The ergodic secrecy capacity is approximated and derived in closed-form expressions.Simulation results validate the accuracy of the analytical and approximate expressions and show the security-enhanced effect of the deployment of the RIS.
