Cheng Wei-ju · Dianzi xuebao · 2014
The end-to-end performance of a dual-hop amplify-and-forw ard relaying system is investigated over composite multipath-lognormal fading channels by using M ixture Gamma( M G) channel model.Novel exact closed-form expressions for the cumulative distribution function and the moment-generation function of the end-to-end signal-to-noise ratio are derived.M oreover,the average symbol error rate,outage probability and the diversity order are found based on the above new expressions,respectively.These expressions are more simple and accuracy than the ones obtained by using GeneralizedK( KG) channel model.Finally,numerical and simulation results are show n to verify the accuracy of the analytical results.
