Optimal Hybrid Beamforming Design for Millimeter-Wave Massive Multi-User MIMO Relay Systems
As a promising technology in the next generation mobile network, millimeter-wave (mmWave) communication can mitigate the spectrum crunch of improving the network capacity by exploiting the large underutilized spectrum bands of the mmWave frequencies.The hybrid (analog/digital) beamforming of multi-data streams are widely used to further the spectru
