作者调查的前向/后向信道记忆（统计依赖的传输错误的发生）ARQ错误控制的效果。为了在性能分析中考虑后向信道差错的影响，他们提出了一些改进的ARQ方案，这些方案具有有效的重传策略，可以防止重传段上的差错引起的死锁。他们认为两个修改的go-back-N计划与定时器控制和缓冲区控制，一个修改的选择性重复计划和一个修改的停止和等待计划。通过分析和仿真结果，他们表明有多少性能的吞吐量和延迟的修改ARQ方案的影响程度的错误突发时，前向和后向信道由一阶马尔可夫块错误模式。它们还表明，在突发错误和独立错误情况下，性能之间存在很大的差异。>
The authors investigate the effect of forward/backward channel memory (statistical dependence in the occurrence of transmission errors) on ARQ error controls. To take into account the effect of backward channel errors in the performance analysis, they suppose some modified ARQ schemes that have an effective retransmission strategy to prevent the deadlock incurred by the errors on acknowledgments. They consider two modified go-back-N schemes with timer control and with buffer control, one modified selective-repeat scheme and one modified stop-and-wait scheme. By analytical and simulation results, they show how much the performance in throughput and delay of the modified ARQ schemes is affected by the degree of error burstiness when the forward and backward channels are governed by a first-order Markovian block error pattern. They also show that there exists a large difference between the performances with the burst and independent error cases. >
