RISs can adjust signals' phase and amplitude, resulting in improved signal strength. In this paper, we investigate the performance of pilot-aided channel estimation for a RIS-assisted wireless communication system over time-varying fading channels. We present numerical results on the effect of the number of pilots and the percentage of pilots per frame on the bit error rate performance.engrestrictedAccessconferenceObject00106257100023510.1109/SIU59756.2023.10224028Pilot-assisted channel estimationTime-varying fading channelsReconfigurable intelligent surfaces2-s2.0-85173433685
