Spatially correlated reconfigurable intelligent surfaces-aided cell-free massive MIMO systems

Published: IEEE Transactions on Vehicular Technology

We study the uplink spectral efficiency (SE) of a practical spatially correlated RISs-aided CF massive MIMO system over Rician fading channels. Specifically, we derive the closed-form expression for characterizing the uplink SE of the system, which shows that increasing the number of RIS elements can improve the system performance.

Wireless energy transfer in RIS-aided cell-free massive MIMO systems: Opportunities and challenges

Published: IEEE Communications Magazine

We study four uplink implementations for CF mMIMO systems with multi-antenna users, from fully centralized processing to fully distributed processing. We observe that the system performance may not always benefit from the number of antennas per user.
