摘要

针对回退n和选择性重复自动重复请求(ARQ)方案，提出了一种自适应控制方法。其过程是根据误码率动态改变连续传输数据块的数量和长度。对半双工传输线的自适应ARQ方案的吞吐量与相应的传统方案的吞吐量进行了比较。数值结果表明，当误码率不确定或随时间变化时，自适应ARQ方案优于传统ARQ方案。

Performance evaluation of adaptive ARQ schemes over half duplex transmission line

An adaptive control procedure is proposed for the go-back-N and selective-repeat automatic repeat-request (ARQ) schemes. The procedure is to dynamically vary the number and length of continuously transmitted data blocks according to the bit error rate. The throughput of the adaptive ARQ schemes for a half-duplex transmission line is compared with the throughput of corresponding conventional schemes. Numerical results indicate that adaptive ARQ schemes are superior to conventional ARQ schemes when the bit error rate is not known or varies with time.<>
