Abstract: Based on multiple-input-multiple-output (MIMO) scattering wireless fading channel model, a dynamic receiving and transmitting model for MIMO wireless channels is proposed in this paper, which is used for analyzing the impact of mobility of transceiver antennas on spatial correlation and capacity of MIMO wireless channels. The results show that the effects are determined by the original positions of transceiver antennas and by their velocity. The simulation results validate this impact and point out that there exists an optimum angular spread that forces spatial correlation, which decreases with increasing antenna spacing and does not consistently decrease with increasing angular spread, to reach minimum.
