Modified MIMO scattering wireless channel model and performance

This article gives a scattering MIMO channel model based on dynamic MIMO scattering channel model considering Doppler effect. According to outdoor wireless MIMO scattering channel model, dynamic MIMO channel model presents the effects of mobility of scatters and transceiver antennas on spatial correlation, which are determined by original positions of transceiver antennas and their velocity. It is necessary to take Doppler effect into account, when the mobile terminal is moving quickly. As a result of the frequency shift due to the Doppler effect, this article gets the spatial correction matrix and channel matrix. The simulation results verify that it is more realistic to take the impact of Doppler effect on the capacity and probability density distribution of the MIMO scattering channel model into account compared with the former.
