Abstract: In this paper, the upper bound on the average symbol error probability (ASEP) of the mobile-relay-based mobile-to-mobile (M2M) system with amplify-and-forward (AF) relaying over N-Nakagami fading channels is investigated. By the pairwise error probability (PEP) approach, the closed-form expressions for the upper bound are derived. The power allocation problem is formulated to determine how the overall transmit power should be shared between broadcasting and relaying phases for performance optimisation. Then, the ASEP performance under different conditions is evaluated through numerical simulations to verify 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 performance.

Keywords: M2M communication; N-Nakagami fading channels; pairwise error probability; PEP; average symbol error probability; ASEP; power allocation.
