Hybrid Beamforming in mm-Wave MIMO Systems Having a Finite Input Alphabet

Recently, there has been significant research effort toward achieving high data rates in the millimeter wave bands by employing large antenna systems. These systems are considered to have only a fraction of the RF chains compared with the total number of antennas and employ analog phase shifters to...
