摘　　要：为准确描述毫米波大规模多输入多输出(MIMO)信道中功率时延可解析性,本文对基于散射簇的3GPP信道建模方法进行扩展,提出了适用于毫米波大规模MIMO信道的一种基于散射簇的空时频非平稳信道模型。针对毫米波大规模MIMO信道中空时频非平稳特性,在基于生灭过程的散射簇演进算法之上,提出空时频散射簇演进算法,从而建模散射簇在空间、时间和频率改变下的变化过程。仿真结果验证了毫米波大规模MIMO信道特性,并与3GPP实测信道数据进行对比,对比结果说明了所构建信道模型的准确性。In order to accurately characterize the power delay resolvability in the millimeter-wave massive multiple input multiple output(MIMO)channel,in this paper the 3GPP scatter cluster-based channel modeling method is extended,and a space-time-frequency non-stationary channel model based on scattering clusters for millimeter-wave massive MIMO channels is proposed.Aiming at the non-stationary characteristics of millimeter-wave massive MIMO channel in space-time-frequency domain,on the basis of the scattering cluster evolution algorithm based on the birth and death process,a space-time-frequency scattering cluster evolution algorithm is proposed,so as to model the changing process of scattering clusters under the changes of space,time and frequency.Simulation results verify the characteristics of the millimeter-wave massive MIMO channel,and the comparison with the measured channel data of 3GPP shows accuracy of the constructed channel model.
