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
