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.
This paper proposes an enhanced opportunistic relay decoding and forwarding protocol which adopts three transmission modes: direct mode, direct repeat mode and opportunistic relay decoding and forwarding mode. The system detects the range of received signal-to-noise ratio through the destination node Select the transmission mode.At the same time, the exact closed-form expression and throughput of the protocol’s interrupt probability performance are given.The theoretical analysis and numerical simulation show that this protocol not only has the high interrupt probability performance of selective opportunistic relay decoding and forwarding, High-throughput performance with enhanced opportunistic relay decoding and forwarding.
