摘要：
In the present study, the performance of digital communication systems operating over a composite fading channel modelled by the generalised-K distribution is analysed and evaluated. Novel closed-form expressions for the outage performance, the average bit error probabilities of several modulation schemes and the channel capacity under four different adaptive transmission schemes are derived. The analytical expressions are used to investigate the impact of different fading parameters of this composite fading channel model on the average bit error rate performance for a variety of digital modulation schemes and the spectral efficiency of different adaptive transmission policies.
