Digital Communications over Generalized-K Fading Channels

In this work, a flexible distribution, called as generalized-K, is used for fading channel modeling. Starting from its probability density function (PDF), useful closed-form expressions for the cumulative distribution function, moments-generating function, moments, and average Shannon´s channel capacity are derived. These expressions are used to study important performance criteria such as the capacity, amount of fading, outage performance, and bit error probability for a great variety of modulation formats. The proposed mathematical analysis is accompanied with various performance evaluation results, which demonstrate the usefulness and flexibility of the proposed model
