Modeling and implementation of space-time-frequency MIMO channel

A multi-tap broadband channel model is established according to Power-Azimuth-Spectrum (PAS), Doppler-Power-Spectral-Density (DPSD), Power-Delay-Profile (PDP) and the antenna structures of both transmitter and receiver. An improved shaping-filter method, which can eliminate correlation of different taps by adding a random phase-shift, is proposed to simulate the independent fading channel. A simulation platform of the wireless MIMO channel is proposed using Matlab, then simulate the MIMO channel model based on 3GPP standard. The simulation results show that the obtained channel characteristics are close to the theory results, which proofs the effectiveness of the improved channel model proposed in the paper.
