In this paper a novelty Massive Multiple Input Multiple Output (MIMO) channel model based on the birth‐and‐death process of multipath clusters is proposed. First, Massive MIMO measurements are conducted in typical outdoSor scenarios with the bandwidth of 100 MHz at frequencies of 1.4725 and 6 GHz, respectively, following with the investigation of radio propagation characteristics over antenna array. Then we research on the subchannel correlation and nonstationary based on the channel sounding experiments. Furthermore, we build up a Markov chain to characterize the birth‐and‐death process of the multipath clusters over the array, which is helpful to bring deeply insight into the cluster evolution over the antenna array axis. And the analysis results are consistent with the theory of the cluster's visible region. At last, the paper systematically demonstrates how does the spatial correlation influence the capacity of the communication system. The whole research work aims to contribute the radio channel modeling of the fifth‐generation (5G) Massive MIMO communication system.

基于空间多径簇生死过程的新颖大规模MIMO信道模型

提出了一种基于多径簇生灭过程的新颖的大规模多输入多输出（MIMO）信道模型。首先，在调查天线阵列上的无线电传播特性之后，在典型的outdoSor场景中分别在1.4725和6 GHz的频率下以100 MHz的带宽进行大规模MIMO测量。然后基于信道探测实验研究子信道的相关性和非平稳性。此外，我们建立了马尔可夫链来表征阵列上多径簇的生灭过程，这有助于深入了解天线阵列轴上的簇演化。分析结果与聚类的可见区域理论吻合。最后，本文系统地说明了空间相关性如何影响通信系统的容量。整个研究工作旨在为第五代（5G）大规模MIMO通信系统的无线信道建模做出贡献。
