Abstract：The massive multiple input and multiple output (Massive MIMO) system,equipped large-scale antenna array in the base station,can greatly improve the data transmission speed and the system capacity and achieve the maximum utilization of the time and space resources.It's of great significance for the application of large-scale antenna and the design of the system to research the wireless communication channel of the Massive MIMO.In this paper,a channel modeling approach based on propagation graph theory is adopted to study the performance of Massive MIMO in the actual propagation channel,which is efficient and able to avoid the heavy workload of practical measurement.For a certain scenario,the channel modeling and simulation is conducted at both 6 GHz and 1.472 5 GHz.The channel impulse response derived from the propagation graph modeling can be further used for parameter extraction.The propagation characteristics of Massive MIMO channel is analyzed from the angle domain,time domain and the singular value decomposition separately.
