Medium-scale or large-scale receive antenna array with digital beamforming can be employed at receiver to make a significant interference reduction but leads to expensive cost and high complexity of the RF-chain circuit. To deal with this issue. classic analog-and-digital beamforming (ADB) structure was proposed in the literature for greatly reducing the number of RF-chains.
