论文摘要
这封信介绍了智能反射表面（IRS）辅助单输出通信系统的详细性能分析，并考虑到发射器和接收器之间的直接链接。沿厄尔及性容量得出了封闭形式的上限，并获得了中断概率的准确近似值。另外，简化的表达式在渐近状态中呈现。提供数值结果以验证理论分析的正确性。已经发现，增加反射元件的数量可以显着提高偏僻的能力和中断概率性能，并且强大的视线组件也有益。另外，希望将IRS部署在发射器或接收器附近，而不是中间。
This letter presents a detailed performance analysis of the intelligent reflecting surface (IRS) aided single-input single-output communication systems, taking into account of the direct link between the transmitter and receiver. A closed-form upper bound is derived for the ergodic capacity, and an accurate approximation is obtained for the outage probability. In addition, simplified expressions are presented in the asymptotic regime. Numerical results are provided to validate the correctness of the theoretical analysis. It is found that increasing the number of reflecting elements can significantly boost the ergodic capacity and outage probability performance, and a strong line-of-sight component is also beneficial. In addition, it is desirable to deploy the IRS close to the transmitter or receiver, rather than in the middle.
