%X In the actual communication environment,the user terminal and surrounding obstacles are often in a mobile state,so the communication environment is often modeled as a time-varying channel. In order to fully study the impact of user mobility on channel characteristics in the current the fifth generation of mobile communications system,a simulation is performed on the non-stationary time-varying channel model and the stationary time-varying channel model based on the 3GPP TR38.901 channel model. The simulations include the power delay spectrum,channel impulse response,channel time-frequency correlation transfer function,delay spread,angle spread and time autocorrelation curves of the two models. Two time-varying models proposed by TR 38.901 are fully studied and simulated,and a detailed comparative analysis is made.
