Energy-Efficient Hybrid Analog and Digital Precoding for MmWave MIMO Systems With Large Antenna Arrays
TL;DR: This paper proposes a successive interference cancelation (SIC)-based hybrid precoding with near-optimal performance and low complexity, and proposes a low-complexity algorithm to realize SIC-based Hybrid precoding, which can avoid the need for the singular value decomposition and matrix inversion.

Energy-Efficient Hybrid Analog and Digital Precoding for mmWave MIMO Systems with Large Antenna Arrays
TL;DR: In this article, the authors proposed a successive interference cancellation (SIC)-based hybrid precoding with sub-connected architecture, which can avoid the need for the singular value decomposition and matrix inversion.
Journal ArticleDOI
Near-Optimal Beam Selection for Beamspace MmWave Massive MIMO Systems
TL;DR: Simulation results verify that IA beam selection can achieve the near-optimal sum-rate performance and higher energy efficiency than conventional schemes.
Journal ArticleDOI
Fast Channel Tracking for Terahertz Beamspace Massive MIMO Systems
TL;DR: Simulation results verify that to achieve the same accuracy, the proposed a priori aided channel tracking scheme requires much lower pilot overhead and signal-to-noise ratio (SNR) than the conventional schemes.
Journal ArticleDOI
Low-Complexity Soft-Output Signal Detection Based on Gauss–Seidel Method for Uplink Multiuser Large-Scale MIMO Systems
TL;DR: This paper proposes to exploit the Gauss-Seidel method to iteratively realize the MMSE algorithm without the complicated matrix inversion, and proposes a diagonal-approximate initial solution to the GS method, which is much closer to the final solution than the traditional zero-vector initial solution.
