Abstract

In this paper, the instantaneous mutual information random process is defined and its second-order statistics such as the autocorrelation and autocovariance functions, level crossing rate, and average outage duration are studied in Rayleigh fading channels with non-isotropic scattering. Closed-form expressions and simple approximate results are derived for the statistics of the instantaneous mutual information random process, and their accuracies are verified via Monte Carlo simulations.
