摘要

Hybrid precoding and combining have been used to reduce the cost and the power consumption of traditional full digital precoding and combining in mmWave MIMO systems. In this paper, we consider a fully-connected hybrid precoding architecture with finite resolution phase shifters. Basically, we first obtain the phases of optimal precoder and combiner, which is obtained through the singular value decomposition (SVD) operation of channel vectors, then these phases are used to construct the RF precoder and combiner. The results show that the proposed algorithm improves the capacity and reduces the complexity compared to the existing orthogonal matching pursuit (OMP)-based algorithm. Besides, an adaptive solution is further proposed to save computational time with competitive performance.
