Abstract :
The mutual information of a wideband Rician fading correlated MIMO channel is approximated by an analytic asymptotic method. The method is applied to derive the optimum input signal covariance matrix and the corresponding ergodic capacity. The numerical accuracy of the method is investigated and the effectiveness of covariance optimization is assessed with respect to the level of spatial correlation and the Rice factor.
