Abstract

This paper analyzes the channel eigenvalue distribution and the ergodic channel capacity of correlated multiple-input multiple-output (MIMO) channels. These eigenvalue densities can be represented by complex hypergeometric functions of matrix arguments, which can be expressed in terms of complex zonal polynomials. A realistic propagation environment in the presence of spatial fading correlation under an outdoor-indoor scenario at 5.25 GHz, which has important applications for data transmission in future cellular as well as wireless local area networks (WLAN) systems, is taken into account to compare to the analytic results. We show that the measured channel matrices of the most practical case of outdoor-indoor can be approximately modelled by the complex Gaussian random matrices with arbitary transmit (TX) covariance matrices. The results from the analytic calculations are in good agreement with those obtained from the measurements.
