Dynamic MIMO scattering wireless channel model and performance

The paper presents a dynamic multiple-input multiple-output (MIMO) scattering wireless channel model based on an outdoor MIMO scattering fading channel model. This dynamic model is used to analyze the effects of the mobility of both scatters and transceiver antennas on the spatial correlation and capacity of MIMO wireless channels. The analysis shows that the effects are determined both by the original positions of transceiver antennas and their velocity and by environments. The simulation results validate the performance of the channel model and show that there exists an optimum angular spread that forces spatial correlation, which decreases with increasing antenna spacing, and does not monotonously decrease with increasing angular spread, to reach minimum.
