A Time-Variant MIMO Channel Model Based on the IMT-Advanced Channel Model

In this paper, a time-variant MIMO channel model is developed based on the IMT-Advanced model. To adjust to the time variant propagation environment, the delays, angles of arrival (AoAs), angles of departure (AoDs) and initial phases, which are taken as constants during a short period of time in the IMT-Advanced model, are extended to the time variant delays, AoAs, AoDs and initial phases. The difference between the new model and the IMT-Advanced model is evaluated by the correlation matrix distance (CMD). The simulation result shows that the correlation of the new model is better than the IMT-Advanced model in time domain.
