摘要

本文考虑了一类具有多帧块和有限重传次数(M)的Go-Back-N ARQ方案的复制-传输有效性，重传块由每个请求帧的多个副本(C)组成。根据传输块所需插槽概率生成函数的精确公式和数值实例，给出了在规定的不可恢复帧错误率容许值范围内，如何确定最大吞吐量和最小块平均传输延迟的C和M。

Effectiveness of copy-transmission in Go-Back-N ARQ system with selective repeat in intra-block and with limited retransmissions

In this paper, we consider the effectiveness of copy-transmission for a class of Go-Back-N ARQ scheme with block of multiple frames and with limited number of retransmissions (M). The retransmitted block is consisted from multiple-copies (C) of each requested frame. Based on the exact formulas of the probability generating function of slots needed to transmit a block and numerical examples, it is shown how to determine C and M for maximizing the throughput and minimizing the average transmission delay of a block within a specified tolerable value of unrecovered frame error rate.
