Abstract mmWave communication system that offers high datarate are accompanied by
massive number of antennas for high gain transmission. These large array of antennas
requires special beamforming schemes and also requires large number of RF chains.
Beamspace MIMO is a beamforming architecture that employs large antenna array and
supports limited number of RF chains by converting conventional mmWave channel into
sparse channel. Multiple antenna array system are susceptible to antenna correlation effect …
