摘要

在多用户大规模多输入多输出（MIMO）系统中，针对传统方案受限于集中式部分连接结构和固定匹配相控算法而未能充分利用空间资源的问题，提出一种基于分布式部分连接结构的低复杂度相控迫零混合预编码方案。所提方案设计了多于射频链路数的逻辑天线子阵列，以使每个射频链路能连接多个分布子阵列，从而提供更高的空间分集增益。进一步通过分析相控模拟预编码对迫零数字预编码的影响，并以最大化系统频谱效率上界为优化目标，提出串行最大化用户总体子阵列增益的相控模拟预编码算法。分析和仿真结果表明，所提方案相较于传统方案在略微增加计算复杂度的前提下能显著提升系统频谱效率，且对非完美信道状态信息不敏感。

Abstract

For multiuser massive multiple-input multiple-output (MIMO) systems

to solve the problem of underutilized spatial resources caused by centralized partially-connected structure (PCS) and fixed-matching phase-control algorithm in conventional schemes

a low complexity phased zero-forcing (PZF) hybrid precoding scheme based on distributed PCS was proposed.The logical antenna subarrays with more than the number of radio frequency (RF) chains were designed

so that each RF chain could be connected to multiple distributed subarrays to provide higher spatial diversity gain.Further

by analyzing the influence of phase-control analog precoding on zero-forcing digital precoding

a phase-control analog precoding algorithm via successively maximizing users’ total subarray gains was proposed to maximize the upper bound of system spectral efficiency.Analysis and simulation results show that

compared with the conventional schemes

the proposed scheme can significantly improve the system spectral efficiency while slightly increases the computational complexity

and it is also insensitive to imperfect channel state information.
