Modeling time-variant multipath characteristics for MIMO channels

This paper has demonstrated the implementation of a time-variant multipath channel model for MIMO applications. The model formulation uses measured channel data to determine the statistical representation of the time-variant multipath cluster characteristics followed by an AR model generation of stochastic realizations of the MIMO channel matrix as a function of time. Comparisons of the information theoretic MIMO performance as a function of time obtained using modeled and measured data show that the model is highly accurate for displacements up to about 10 cm, with the error then growing for larger displacements beyond this 10 cm threshold.
