Abstract: Due to the rapid movement of transmitter and receiver, the propagation channel of mobile communication system performs non-stationary characteristics. A new nonstationary multiple-input multiple-output (MIMO) channel model between base station and mobile station under three dimensional (3D) scenarios is proposed. The new model takes the continuity of fading phase into account and guarantees more realistic Doppler frequency. Meanwhile, an extended 3D time evolving algorithm of channel parameters, including birth-death processes of clusters, path delays, path powers and angles of arrival and departure, is given and analyzed. Simulation results demonstrate that our channel model can characterize the properties of non-stationarity and the time-variant autocorrelation function (ACF) and cross-correlation function (CCF) in a good consistence with theoretical ones, and is applicable to the performance evaluation and validation of wireless mobile system under time-variant 3D scenarios.

Key words: non-stationary channel, multiple-input multiple-output (MIMO) channel, birth-death process, correlation function, Doppler frequency
