In this system, it is impossible to guarantee successful transmission of every data due to instant deep fading. Hence, in order to achieve efficient and reliable transmission, we exploit potential advantage provided by the cooperative diversity and propose a cooperative joint subcarrier and power allocation scheme that minimizes the probability of multicast transmission failure. This combinable allocation issue has high computational complexity, so we allocate subcarrier and power separately. We proposed cooperative proportional subcarrier allocation strategy to achieve tradeoff between throughput and fairness and iterative power (IP) allocation strategy to fully utilize the limited power. Simulation results show that system performance of the schemes with cooperation is significantly enhanced compared with that without cooperation and the schemes with IP remarkably outperform that without.
