Joint Active and Passive Beamforming for RIS-aided MIMO Communications with Low-Resolution Phase Shifts
Nuno Souto
Practical hardware limitations often impose a reduced number of available phase shifts at the elements of a reconfigurable intelligent surface (RIS). Most works often assume contin…

Optimizing the Achievable Rate in MIMO Systems Assisted by Multiple Reconfigurable Intelligent Surfaces
Nuno Souto, João Carlos Silva
In recent years there has been a growing interest in reconfigurable intelligent surfaces (RISs) as enablers for the realization of smart radio propagation environments which can pr…
