| Abstract: | For improving performance of cooperative communication system,the Multi-points relaying cooperative communication systems is analyzed.Exact and closed-form expressions of average symbol error rate(SER) and outage probability with Rayleigh fading channels is firstly derived by means of the Moment Generating Function(MGF) with hyper-geometric function.Simulation results show that the expressions are valid and the performance is better than that of single point relaying cooperative communication. |

| Keywords: | cooperative communication moment generating function transmit diversity hypergeometric function symbol error rate |
