摘　　要：针对大规模MIMO通信系统研究了一种基于码本的有限反馈大规模3D MIMO多用户传输方法,给出一种基于水平和垂直方向码字直积的3DMIMO码书设计方案,并提出了两种垂直码本设计方法,且在合理的调度方案下,对所设计的码本进行了仿真分析。仿真表明本文所提的三维码本相对于二维码本以及传统的三维DFT直积码本,提高了系统频谱利用率和吞吐量性能。A codebook based limited feedback transmission scheme is investigated for downlink multiuser massive MIMO system.A 3D MIMO codebook design method is proposed based on Kronecker product of codewords in the horizontal and the vertical domains to focus on two vertical codebook design.Simulation analysis is made for the proposed 3D MIMO codebook with reasonable scheduling scheme.Simulation shows that the system spectral efficiency and throughput performance of the proposed 3D MIMO codebook are significantly improved compared with 2D codebook and traditional 3D MIMO DFT codebook.
