In this work, the performance of reconfigurable intelligent surface (RIS)-aided communication systems corrupted by the co-channel interference (CCI) at the destination is investigated. Assuming Rayleigh fading and equal-power CCI, we present the analysis for the outage probability (OP), average bit error rate (BER), and ergodic capacity. In addition, an asymptotic outage analysis is carried in order to obtain further insights. Our analysis shows that the number of reflecting elements as well as the number of interferers have a great impact on the overall system performance.

干扰受限的RIS辅助网络的性能分析

在这项工作中，研究了受目的地同信道干扰 (CCI) 破坏的可重构智能表面 (RIS) 辅助通信系统的性能。假设瑞利衰落和等功率 CCI，我们给出了对中断概率 (OP)、平均误码率 (BER) 和遍历容量的分析。此外，为了获得进一步的见解，进行了渐近中断分析。我们的分析表明，反射元件的数量以及干扰源的数量对整体系统性能有很大影响。
