在这项工作中,我们研究了可重构智能表面(RIS)辅助无人机(UAV)系统的性能,其中RIS安装在无人机上,以将信号从天空反射到地面用户。更具体地说,我们提出了两种不同的方法来表示概率密度函数(PDF)的瞬时信噪比(SNR)。利用这两种分布,分别推导出中断概率、平均误码率和平均和速率的封闭表达式。此外,我们还对无人机的最佳飞行高度和位置进行了分析。最后给出了数值结果来验证我们的分析。
In this work, we study the performance of a reconfigurable intelligent surface (RIS)-aided unmanned aerial vehicle (UAV) system where an RIS is installed on a UAV to reflect the signal to the ground user from the sky. More specifically, we present two different methods to denote the probability density functions (PDFs) of the instantaneous signal-to-noise ratio (SNR). With these two distributions, closed-form expressions for the outage probability, average bit error rate (BER), and average sum-rate are derived, respectively. Additionally, we develop the analysis on the optimal UAV altitude and location. Finally, numerical results are given to verify our analysis.
