摘      要：In millimeter wave(mmWave)systems,desirable spectral efficiency can be realized by the hybrid beamformer in which a large sized analog beamformer and a small sized baseband digital beamformer are cascade-connected together to reduce the system ***,most of works focus on the beamforming(or combining)method design with an impractical analog beamformer where the infinite-resolution phase shifts(PSs)are *** this paper,a more practical hybrid beamformer with low-resolution PSs is considered and the hybrid receiver beamforming method under the multiuser uplink communication circumstance is *** the system performance is mainly constrained by the interuser interference,we propose a novel two-stage hybrid receiver beamforming against the inter-user interference with comparable computational complexity than that of the recently presented ***,to enhance the performance of systems with many users,we propose a novel multiuser selection algorithm by exploiting the multiuser diversity ***,from the simulation results,we can verify the superiority of the proposed method over the comparing method in error probability and spectrum efficiency.
