Abstract
This paper presents new exact closed-form expressions for the outage probability of cellular systems (without diversity reception) in which the desired user follows a Rician distribution whereas the interferers are subject to correlated Rayleigh fading. It then capitalizes on a numerical technique by Raphaeli dealing with the accurate evaluation of the cumulative distribution function of quadratic forms in complex Gaussian random variables to solve for the outage probability in the more general case of arbitrary fading statistics, average fading powers, diversity branches correlation, and/or correlation between the interferers. In some scenarios the numerical approach reduces to finite-sum closed-form expressions.
