| 摘 要： | 在干扰对中继节点和目的节点都产生影响时，根据是否考虑直接传输，提出了2种最小化中断概率的机会中继协议. 考虑直接传输时，目的节点采用最大比值合并直接传输和中继传输. 推导了2种机会中继协议在独立不同分布瑞利信道中的中断概率. 仿真结果表明，就中断概率而言,考虑干扰的机会中继优于不考虑干扰的机会中继，考虑直接传输的机会中继优于不考虑直接传输的机会中继.

| Abstract: | Because of interference between both the relays and the destination,the two opportunistic relaying protocols are proposed to minimize the outage probability according to whether the direct transmission is considered or not. Moreover,if the direct transmission is taken into account,maximal ratio combining is deployed at the destination to combine the direct transmission and relay transmission. The outage probabilities of the protocols are derived over the independent non-identically distributed Rayleigh fadi... |
