摘　　要：协同通信是近几年无线通信技术的研究热点,协同中继的选择策略直接影响到协同通信系统的性能。文章以多节点协同通信网为系统模型,研究了两种改进的机会选择策略,分析推导了该策略的中断概率的近似表达式,结果表明,这两种策略均可以获得比传统的机会选择策略更好的中断概率性能。Cooperative communication is a promising technique to improve high data-rate coverage in future communication systems.The strategies about selection relays have a huge effect on the performance of system.In this paper,we study two improved strategies about selection relaying protocols with opportunistic relaying.Moreover,the asymptotic outage probability is derived.Results show that the outage probability of the two strategies outperforms traditional opportunistic relaying.
