Performance Analysis of IDF Relaying M2M Cooperative Networks over N-Nakagami Fading Channels

In this paper, the performance of fixed-gain amplify-and-forward (FAF) relaying is investigated. An approximation for the average symbol error probability (SEP) is derived for multiple-mobile-relay-based mobile-to-mobile (M2M) cooperative networks over NNakagami fading channels. The moment generating function (MGF) method is used to obtain average SEP expressions for various modulation techniques. The performance under different conditions is evaluated through numerical simulation to verify the analysis. These results show that the number of mobile relay nodes, the fading coefficient, the number of cascaded components, the relative geometrical gain, and the power allocation parameter have a significant impact on the SEP performance.
