论文摘要
可重新配置的智能表面（RIS）辅助无人机车辆（UAV）通信已被确定为许多下一代应用程序的关键推动者。但是，据我们所知，没有通用的框架来量化RIS辅助无人机系统的吞吐量性能。在本文中，我们提出了一个全面的系统模型，该模型解释了多径褪色的影响，多径褪色的影响是通过混合伽玛，收发器硬件缺陷以及随机光束失调和未对准的模型，以检查RIS辅助无人无关无无无无无无无无ere的系统的吞吐量。在这个方向上，我们为系统的吞吐量提供了一种新颖的闭合表达：i）在存在的情况下，ii）在没有迷失方向和未对准的情况下。有趣的是，我们的结果揭示了上述现象的准确建模以及最佳传输光谱效率的存在的重要性。
Reconfigurable intelligent surface (RIS)-assisted unmanned areal vehicles (UAV) communications have been identified as a key enabler of a number of next-generation applications. However, to the best of our knowledge, there is no generalized framework for the quantification of the throughput performance of RIS-assisted UAV systems. Motivated by this, in this paper, we present a comprehensive system model that accounts for the impact of multipath fading, which is modeled by means of mixture gamma, transceiver hardware imperfections, and stochastic beam disorientation and misalignment in order to examine the throughput performance of a RIS-assisted UAV wireless system. In this direction, we present a novel closed-form expression for the system's throughput for two scenarios: i) in the presence and ii) in the absence of disorientation and misalignment. Interestingly, our results reveal the importance of accurate modeling of the aforementioned phenomena as well as the existence of an optimal transmission spectral efficiency.
