Abstract

In this paper, the capacity of multiple-input multiple-output (MIMO) systems over a Rician fading channel is evaluated. We show that the capacity of MIMO Rician channels can be well approximated by that of correlated MIMO Rayleigh channels. We take the Rician channel with rank-1 mean matrices as an example, the asymptotic capacities at low and high signal- to-noise ratio (SNR) regions are analyzed. Finally, the asymptotic capacity loss of Rician channels relative to Rayleigh channels is derived.
