论文摘要
本文研究了通过智能反射表面（IRS）增强的单输入单输出（SISO）系统的性能，该系统在瑞利褪色通道下配备了有限数量的元素。从瞬时通道容量中，我们仅计算覆盖概率的封闭形式表达，仅是统计通道信息的函数。进一步获得了覆盖率概率和相移数的缩放定律。梯形容量被得出，然后简单的上限来简化利用符号功能的问题，并可以长时间应用。与蒙特 - 卡洛模拟相比，数值结果表明了我们封闭形式表达的紧密度和有效性。
This paper studies the performance of a single-input single-output (SISO) system enhanced by the assistance of an intelligent reflecting surface (IRS), which is equipped with a finite number of elements under Rayleigh fading channels. From the instantaneous channel capacity, we compute a closed-form expression of the coverage probability as a function of statistical channel information only. A scaling law of the coverage probability and the number of phase shifts is further obtained. The ergodic capacity is derived, then a simple upper bound to simplify matters of utilizing the symbolic functions and can be applied for a long period of time. Numerical results manifest the tightness and effectiveness of our closed-form expressions compared with Monte-Carlo simulations.
