A Family of Hybrid Analog-Digital Beamforming Methods for Massive MIMO Systems

In massive MIMO systems, hybrid beamforming is an essential technique for exploiting the potential array gain without using a dedicated RF chain for each antenna. In this paper, we consider the data phase in massive MIMO communication, where the transmitter and receiver use fewer RF chains than ante...
