Abstract

The symbol error rate (SER) performance of decode-and-forward (DF) relay cooperative system over flat Rayleigh fading channels is analyzed in this paper. Using the moment generating function (MGF) based analysis approach, the closed-form expressions for the average SER of coherently detected M-ary phase-shift keying (MPSK) for the system are derived. In addition, the SER performance of system with no cooperation is also given to compare with that with relay cooperation. Numerical results show that better SER performance can be achieved by increasing the average receive signal-to-noise ratio (SNR), and the SER performance of system with DF cooperation is better than that with no cooperation. The correctness of theoretical analysis is verified by simulation results.
