摘要：

Due to its ability to effectively and intelligently adapt to the propagation environment, reconfig-urable intelligent surface (RIS) is considered an enabling technology for future wireless networks. In this paper, within the energy efficiency (EE) and spectral efficiency (SE) context, we conduct a detailed performance analysis and a comparison of a RIS-assisted wireless communication system with two other setups, namely a decode-and-forward (DF) relaying-assisted setup and a basic single-input, single-output (SISO) setup. The simulation results along with the analytical ones reveal that both a correct power modeling and allocation and a correct choice of the number of the RIS reflective elements have a crucial role in the EE-SE trade-off. © 2023 by Begell House, Inc.
