{"cited_by_count":536216,"description":"This cluster of papers focuses on the application of intelligent reflecting surfaces (IRS) and reconfigurable intelligent surfaces (RIS) in wireless communication systems, particularly in the context of non-orthogonal multiple access (NOMA), 6G networks, and MIMO systems. The papers explore topics such as beamforming optimization, channel estimation, energy efficiency, and the use of IRS for creating smart radio environments.","display_name":"Advanced Wireless
