Hybrid Beamforming for Large Antenna Arrays with Phase Shifter Selection
Sohail Payami, Mir Ghoraishi, Mehrdad Dianati
This paper proposes an asymptotically optimal hybrid beamforming solution for large antenna arrays by exploiting the properties of the singular vectors of the channel matrix. It is…
