Phase Shifter Optimization in RIS-Aided MIMO Systems Under Multiple Reflections
Phase Shifter Optimization in RIS-Aided MIMO Systems Under Multiple Reflections is a scholarly work, published in 2024 in ''IEEE Transactions on Wireless Communications''. The main subjects of the publication include Phase shift module, electronic engineering, Underwater acoustic communication, telecommunications, MIMO, antenna, phase, and computer science. The authors examine the problem of joint active and passive beamforming in a controllable multi-user reconfigurable intelligent surface (RIS)-assisted downlink and uplink wireless communication system, considering the mutual coupling among RIS elements.
