End-to-End Performance Analysis of AF Relaying M2M Cooperative System

In this paper, the end-to-end performance of the mobile-relay-based mobile-to-mobile (M2M) system with amplify-and-forward (AF) relaying over N-Nakagami fading channels is investigated. The exact closed-form expressions for the lower bound on average symbol error probability (ASEP) and upper bound on channel capacity are derived. Then the ASEP and channel capacity performance under different conditions is evaluated to confirm the accuracy of the analysis. Results are presented which show that the fading coefficient, the number of cascaded components, the relative geometrical gain, and the power-allocation parameter have an important influence on the ASEP and channel capacity performance.
