A Universal Hybrid Precoding Scheme for Massive MIMO Communications
文献摘要：
Based on an analog radio frequency(RF)network,hybrid precoding(HPC)for massive MIMO can achieve very high spectral efficiencies with mod-erate hardware cost and power consumption.Despite the extensive research efforts in recent years,the prac-tioners are still looking for HPCs that are efficient and easy-to-implement.In this paper,we present a new method termed as the universal hybrid precoding(UHP),which is nearly optimal,computationally effi-cient,and applicable to various types of RF network(thus,the name universal):the components of the net-work can be phase shifters(with finite or infinite res-olutions),switches,or their combinations;the topol-ogy of the network can be fully-connected or partially-connected.Besides the standard UHP,we also propose a simplified version termed as sUHP to trade a neg-ligible performance loss for much reduced computa-tional complexity.The analysis shows that the compu-tational complexity of the proposed UHP/sUHP is one to two orders of magnitude lower than the state-of-the-art methods.Simulation results verify the(near-)opti-mality of the proposed UHP scheme for various forms of the analog networks.
