Hybrid Beamforming for Multi-User Millimeter-Wave Networks
IEEE Transactions on Vehicular Technology, 2020 This paper considers hybrid beamforming by combining an analog beamformer with a new regularized zero forcing baseband one, for multi-user millimeter-wave networks under a limited number of radio frequency (RF) chains. Three popular scenarios are examined: i) the number of users is up to the number of RF chains in a single-cell network, ii) the number ...
