Abstract

The application relates to the technical field of channel modeling, and provides a non-stationary cluster delay line channel modeling method and device based on cluster evolution. The application uses a Markov process to represent the birth-death process of each cluster, thereby describing the non-stationary characteristics of a multi-antenna channel in a city. Meanwhile, in the birth-death process of each cluster, the cluster power is smoothed by using a cluster power evolution function and sampling time in the current birth-death interval, the cluster power is smoothed by introducing double-time parameters of birth-death time and sampling time, the problem of stepwise jump of cluster power in a traditional model is solved, the power attenuation of a channel impulse response is more in line with the physical law of actual propagation, and the modeling error caused by power mutation is reduced.
