论文摘要
可重新配置的智能表面（RIS）由于其通过反射对接收器的信号扩展细胞覆盖的能力而受到了越来越多的关注。本文考虑了RIS辅助高速列车（HST）通信系统，以提高覆盖范围的概率。我们得出了覆盖概率的封闭形式表达。此外，我们分析了某些关键系统参数的影响，包括传输功率，信噪比阈值以及基站和RIS之间的水平距离。仿真结果验证了RIS辅助HST通信的效率，从覆盖率概率方面。
Reconfigurable intelligent surface (RIS) has received increasing attention due to its capability of extending cell coverage by reflecting signals toward receivers. This paper considers a RIS-assisted high-speed train (HST) communication system to improve the coverage probability. We derive the closed-form expression of coverage probability. Moreover, we analyze impacts of some key system parameters, including transmission power, signal-to-noise ratio threshold, and horizontal distance between base station and RIS. Simulation results verify the efficiency of RIS-assisted HST communications in terms of coverage probability.
