论文摘要
在本文中，我们分析了可重新配置的智能表面（RIS）辅助无人机（UAV）无线系统的性能，该系统受混合物粉末褪色，随机迷失方向和失误的影响，以及经传递器硬件易局。首先，我们从统计上表征两种情况的端到端通道，即，在缺乏和存在迷失方向和未对准的情况下，通过提取概率密度函数（PDF）和累积分布函数（CDF）的闭合形式公式（CDF）。在上述表达式的基础上，我们在不存在和存在迷失方向和未对准以及硬件瑕疵的情况下提取新颖的封闭形式表达式（OP）。另外，得出了高信噪比OP近似值，从而导致多样性顺序提取。最后，出现了由于迷失方向和未对准而引起的OP地板。
In this paper, we analyze the performance of a reconfigurable intelligent surface (RIS)-assisted unmanned aerial vehicle (UAV) wireless system that is affected by mixture-gamma small-scale fading, stochastic disorientation, and misalignment, as well as transceivers hardware imperfections. First, we statistically characterize the end-to-end channel for both cases, i.e., in the absence as well as in the presence of disorientation and misalignment, by extracting closed-form formulas for the probability density function (PDF) and the cumulative distribution function (CDF). Building on the aforementioned expressions, we extract novel closed-form expressions for the outage probability (OP) in the absence and the presence of disorientation and misalignment as well as hardware imperfections. In addition, high signal-to-noise ratio OP approximations are derived, leading to the extraction of the diversity order. Finally, an OP floor due to disorientation and misalignment is presented.
