【摘要】 提出了一种增强选择性机会中继解码转发协议,采用了3种传输模式:直传模式,直接重复传输模式和机会中继解码转发模式,系统通过目的节点检测接收到的信噪比范围来选择传输模式.同时,给出了该协议的中断概率性能的精确闭式表达和吞吐量.通过理论分析和数值仿真表明:该协议不仅具有选择性机会中继解码转发的高中断概率性能,而且兼具增强型机会中继解码转发的高吞吐量性能.

【Abstract】 The problem of accurate closed-form expression for the outage probability derived was pointed out.Additionally,an incremental selective opportunistic relaying decode-and-forward(ISODF) protocol was proposed.In this protocol,there are three transmission modes,which are direct transmission,direct repeat transmission and opportunistic relaying decode-and-forward.The transmission mode can be selected by detecting the signal-to-noise ratio(SNR) received by the destination.Furthermore,exact closed-form of the outage probability and throughput of the considered protocol were derived.Theoretical analysis and simulation results show that the proposed protocol has the high outage performance as selective opporunistic decode-and-forward protocols(ODF) and the high throughput as incremental ODF.
