Abstract

The utilization of millimeter wave (mmWave) frequency has shown great potential for future wireless cellular systems. Compared with conventional fully digital precoding, hybrid precoding achieves a high performance with less radio frequency (RF) chains and lower hardware complexity. In this paper, we investigate the hybrid precoding for multiuser communication in a downlink mmWave massive MIMO system. First, we present a hybrid precoding scheme designed based on zero-forcing (ZF) precoding. Then, we derive the spectral efficiency of this hybrid precoding scheme and get its closed-form expression which can be represented by the digamma function. Finally, simulation results demonstrate the validity of the analytical result.
