Abstract
Taking into account realistic propagation environments, in the presence of spatial fading correlation at both the transmitter and the receiver, we derive closed-form analytical expressions for the exact characteristic function and statistical moments (mean, variance, skewness, and kurtosis) of instantaneous capacity for multiple-input multiple-output (MIMO) wireless channels. These results enable us to analytically evaluate two relevant information-theoretic capacity measures - ergodic and outage capacity - and other higher-order statistics of the capacity. We also analyze the multi-user scheduling gain in rate-feedback systems using the Gaussian approximation to the capacity distribution.
