摘要

基于透镜天线阵列的毫米波大规模MIMO系统，可以在不损失性能的情况下，有效减少所需的射频链数。为了解决现有波束空间信道中的功率泄露和多用户干扰问题，提出了一种联合QR分解和波束增益对准（beam gain alignment，BGA）的混合预编码方案。首先，设计了一种移相网络（phase shift network，PSN）结构，使得波束空间MIMO中的每个射频链能够选择多个波束来收集泄露功率。其次，对波束信道矩阵进行QR分解，以可达和速率为目标，按照递增顺序逐一选择合适的波束，直至选出最优波束选择矩阵。最后利用波束增益对准策略设计模拟预编码，为了消除系统中的多用户干扰，设计了一种使信道对角化的数字预编码器。仿真结果表明，所提算法有着更低的复杂度以及更高的可达和速率及能量效率。

Abstract

Millimeterwave massive MIMO systems based on lens antenna arrays can effectively reduce the number of required RF chains without loss of performance. In order to solve the problems of leakage power and multiuser interference in existing beamspace channels

a hybrid precoding scheme was proposed that combining QR decomposition and beam gain alignment (BGA). Firstly

a phase shift network (PSN) structure was designed

so that each RF chain in beamspace MIMO can select multiple beams to collect the leakage power. Secondly

QR decomposition was performed on the beam channel matrix

with the achievable sum rate as the goal

and appropriate beams were selected one by one in increasing order until the optimal beam selection matrix was selected.Finally

the beam gain alignment (BGA) strategy was used to design the analog precoding. In order to eliminate multiuser interference in the system

a digital precoder was designed to diagonalize the channel. Simulation results show that the proposed algorithm has lower complexity and higher achievable sum rate and energy efficiency.
