Abstract

In the Rayleigh fading channel, this paper compares the communication performance of a reconfigurable intelligent surface (RIS)-assisted communication system and the traditional relay system in terms of amplify-and-forward (AF) and decode-and-forward (DF) protocols. First, the closed expressions of the outage probability (OP), average bit error rate (BER), and average system channel capacity under different conditions are given. Furthermore, we compare the probability of signal-to-noise ratio (SNR) gain in the three modes. Numerical results show that the RIS-assisted communication system has obvious advantages over traditional relays in performance. In addition, the performance of the systemsystem's performance is improved obviously with the increase of the number of reflector surfaces.
