Abstract

Reconfigurable intelligent surface (RIS) technology uses electronically tunable surfaces in the far field of the transmit antenna for the purpose of beamforming towards receiver of interest. Media-based modulation (MBM) uses such surfaces in the near field of the transmit antenna for the purpose of modulation. RIS-aided MBM offers improved communication performance at low radio-frequency (RF) hardware complexity, combining the good attributes of both RIS and MBM. In this paper, we analyze the performance of RIS-aided MBM in the presence of imperfect channel state information (CSI) at the receiver and phase tuning errors at the RIS. We derive expressions for pairwise error probability and bit error probability for RIS-aided MBM with imperfect CSI and phase tuning errors. Bit error rate performance results obtained through analysis and simulations are presented. Results show improved bit error performance for increased number of RIS elements. © 2023 IEEE.
