14407 在重传阶段,发送终端在立即可解网络编码(Instantly Decodable Network Coding, IDNC)图上根据接收终端与发送终端的链路质量、终端数据包权重和接收终端的连通度选择出发送终端的最优编码包,以降低系统的平均解码时延。 In the retransmission phase,the transmitting terminal selects the optimal coding packet of the transmitting terminal on the instantly decodable network coding( IDNC) diagran according to the link quality between the receiving terminal and the transmitting terminal, the terminal packet weight and the connectivity of the receiving terminal,so as to reduce the average decoding delay of the sys- tem.
14408 同时,利用部分接收终端对最优编码包的无效解码和不可解码的特性,扩展了备选协作终端,使更多的终端参与到协作传输过程。 At the same time,taking advantage of the invalid decoding and undecodability of the optimal coding packet by some receiving terminals ,the alternative cooperative terminals are extended to make more terminals participate in the cooperative transmission process.
