On Spatial Multiplexing Using Reconfigurable Intelligent Surfaces
Mohamed A. ElMossallamy, Hongliang Zhang, Radwa Sultan +4
We consider an uplink multi-user scenario and investigate the use of reconfigurable intelligent surfaces (RIS) to optimize spatial multiplexing performance when a linear receiver i…
