Energy Efficiency Enhancement in User-Centric and Cell-Free Millimeter-Wave Massive MIMO Systems With Hybrid Beamforming

Cell-free massive multiple-input multiple-output (CF-mMIMO) is a new and scalable network architecture that can bring antennas closer to users. In addition, hybrid beamforming can greatly reduce the power consumption by limiting the number of radio frequency chains. To achieve higher energy efficien...
