STAR-RIS-Assisted MIMO-MAC Over Spatially Correlated Rician: Sum-Rate Analysis and Optimization

Simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS) can intelligently control the electromagnetic waves in the whole space through its passive components, thereby enhancing the wireless propagation environment, which is considered to be a promising technology. This paper studies th...

Spectral Efficiency Enhancement for Spatially Non-Stationary XL-RIS-Aided Systems With Dual-Side VR Estimation

This letter investigates spatial non-stationarities at both the reconfigurable intelligent surface (RIS) and base station, where only partial arrays, referred to as the visibility region (VR), can receive user signals. To improve spectral efficiency (SE) in frequency division duplexing systems, we embed VR estimation i...
