Performance analysis of threshold digital relaying M2M cooperative networks

Abstract

Exact average bit error probability (BEP) expressions for mobile-to-mobile cooperative networks employing threshold digital relaying over N-Nakagami fading channels are derived. The power allocation problem is formulated for performance optimization. The average BEP performance is evaluated via numerical simulation to verify the accuracy of the analysis with binary phase shift keying (BPSK) modulation. The simulation results showed that the fading coefficient, number of cascaded components, relative geometrical gain, and power-allocation parameter have a significant influence on the performance.
