研究了非独立信道差错对自动重传请求（ARQ）协议性能的影响。这些协议是三种基本的ARQ协议：停止等待、返回N和选择性重复。考虑了两种非独立信道误差：k阶马尔可夫误差和差距误差。吞吐量效率和分组延迟。计算机仿真验证了分析的正确性。一个关键的发现是，当信道错误是相关的，选择性重复ARQ实现相同的吞吐量效率，在独立的信道错误。>
The performance of automatic-repeat-request (ARQ) protocols which are affected by nonindependent channel errors is studied. The protocols are the three basic ARQ protocols: stop-and-wait, go-back-N, and selective-repeat. Two types of nonindependent channel errors are considered: the kth-order Markovian errors and the gap errors. Both throughput efficiency and packet delay are obtained. The validity of analysis is verified by computer simulations. One key discovery is that when channel errors are dependent, selective-repeat ARQ achieves the same throughput efficiency as that in independent channel errors. >
