Abstract

In order to improve the beamforming gain of millimeter-wave massive MIMO system and reduce the hardware cost of antenna and phase shifter, this paper proposed a hybrid precoding design scheme based on discrete phase shifter. Aiming at optimizing spectral efficiency of the system, this scheme considered the spatial characteristic precoding design of millimeter wave channel as spatial sparse reconstruction problem according to the response of uniform linear array and uniform planar array, which used discretized orthogonal matching tracking principle to obtain the digital precoding and discretization of analog precoding. The simulation results show that the spectral efficiency of the planar array is better than that of the linear array under the same conditions. At the same time, the performance of the low-precision phase shifter in the proposed discretization hybrid precoding scheme almost reaches the performance gain of the full-precision phase shifter.
