Outage probability analysis in cellular systems with noisy Weibull-faded lognormal-shadowed links

We consider the problem of determining the outage probability in cellular systems where each of the links is lognormal-shadowed, Weibull-faded and corrupted by additive noise. We propose two solutions for this problem; a simple lower bound on the outage probability based on the concavity of the logarithmic function and an approximate expression based on the use of the central limit theorem. The approximate expression is slightly more complicated than the lower bound but provides a better accuracy for most of the parameters values. We verify the accuracy of the proposed expressions by comparing them to the outage probability obtained by means of Monte Carlo simulations.
