摘　　要：提出了考虑多个干扰的解码转发主动机会中继选择协议.针对存在直通链路的中继模型,在多个干扰对中继节点和目的节点同时产生影响的情况及独立不同分布的瑞利信道环境下,推导出了目的节点采用最大比合并时的中断概率,并对结果进行了仿真验证.在存在多个干扰的情形下,考虑干扰的中继选择方案优于经典的中继选择方案,中继选择协议可以减少干扰对系统的影响.A proactive decode-and-forward opportunistic relay protocol with multi-interference at the relays and the destination is proposed. The maximum ratio combining scheme is deployed at the destination where direct link is considered. And the outage probabilities over the independent non-identical Rayleigh fading channels is derived with multi-interference affected relay and destination nodes. Monte-Carlo simulations are requested to verify the analysis. Furthermore, it is concluded that relay selection protocols considering the multiple interference nodes are much better than the schemes without considering the interference. The proposed protocols can reduce the effect of interference on the system.
