在这封信中，我们提出了解码和转发基于协作组播系统的中断性能与最佳中继选择（CM-RS）在瑞利衰落信道。特别地，我们给出了CM-RS中断概率及其分集阶数的精确封闭表达式。通过数值计算验证了分析的正确性，并与单跳组播系统的中断性能进行了比较。
In this letter, we present the outage performance of decode-and-forward based cooperative multicast systems with the best relay selection (CM-RS) over Rayleigh fading channels. Especially, we provide an exact and closed-form expression for the outage probability of CM-RS and its diversity order. Through numerical results, the analysis is verified, and the outage performance of CM-RS is compared with that of a single-hop multicast system.
