A coded cooperation protocol based on Turbo codes is proposed for multi-relay wireless networks,in which the opportunistic cooperative strategy is to determine the relay node depends on the information of channel condition.The system outage performance is analyzed and the outage probability expression for Rayleigh fading is given.Numerical comparison show the relative merits between opportunistic coded cooperation and traditional coded cooperation.
