Low-complexity Multicast Beamforming for Multi-stream Multi-group Communications
Hamidreza Bakhshzad Mahmoodi, Bikshapathi Gouda, MohammadJavad Salehi +1
In this paper, assuming multi-antenna transmitter and receivers, we consider multicast beamformer design for the weighted max-min-fairness (WMMF) problem in a multi-stream multi-gr…
