A Stochastic Model of Channel Correlation in MIMO Systems

This paper presents a simple stochastic model of MIMO channel for Monte Carlo simulation. This model includes a partial correlation between the paths in the channel. The authors substantiated the way of achieving proper correlation coefficients according to the proposed solution. The input parameter to the proposed model is either a full correlation matrix for the channel obtained from the physical channels measurements or an arbitrary set. The paper comprises also a comparison with popular channel models (Kronecker, Weichselberger) and the comparison of BER performances and average mutual information obtained for channels generated according to mentioned models.
