Combined DL-UL Distributed Beamforming Design for Cell-Free Massive MIMO
Bikshapathi Gouda, Antti Arvola, Italo Atzeni +1
We consider a cell-free massive multiple-input multiple-output system with multi-antenna access points (APs) and user equipments (UEs), where the UEs can be served in both the down…
