In particular, we focus on a RISassisted wireless transmission in which imperfect phase errors are modeled by the Tikhonov distribution. The source (S) and destination (D) nodes are equipped with a single antenna, and the channels between the S-RIS and RIS-D nodes exhibit Rayleigh fading which is a good fit for the non-line-of-sight instances. For this system, we derive novel and exact analytical and asymptotic expressions for the ASEP, and the obtained ASEP expressions are then exploited to evaluate the error performance of under different network configurations. The proposed theoretical analysis is confirmed through the exact simulation results.eninfo:eu-repo/semantics/closedAccessReconfigurable intelligent surfaceAverage symbol error probabilityRayleigh fadingArticleQ1171WOS:001080696300001Q2
