摘　　要：为建立适用大规模MIMO系统性能分析和评估的信道模型,提出了一种3D Massive MIMO Kronecker信道模型。在传统3D MIMO Kronecker信道模型研究基础上,利用生灭过程建模散射簇在阵列轴的非平稳演变来表征Massive MIMO信道的非平稳特性,将生灭过程的影响抽象为幸存概率矩阵。通过仿真实验可以验证,所提信道模型不仅能够表征大规模天线阵列的空间相关性,而且可以描述散射簇在大规模天线阵列轴上的演变。To establish a rational channel model for performance analysis and evaluation suitable for massive multipleinput multiple-output(MIMO)system,this paper proposes a 3D Massive MIMO Kronecker channel model.On basis of the study of traditional 3D MIMO Kronecker channel model,the non-stationary characteristics of Massive MIMO channel are characterized by using the birth-death process to model the non-stationary evolution of scattering clusters on the array axis.The birth-death process is abstracted as the survival probability matrix.Simulation results show that the proposed channel model can not only capture the spatial correlation of large-scale antenna arrays,but also describe the evolution of scattering clusters on the large-scale antenna array axis.
