摘要
本文提出一种把连续发送与SW ARQ相结合的部分请求重传ARQ差错控制体制。该体制使用半双工信道,与GBN ARQ比较可节省传输频带。文中对该系统的性能进行了分析。结果表明,其误码率与SW或GBN ARQ的误码率相近,通过率比SW ARQ的通过率高得多,接近于GBN ARQ的通过率。该体制具有较好的性能和一定的实用价值。
In this paper, a part repeat ARO error control system of combined continuous transmission pattern with SW ARQ pattern is considered. The system transmited data by means of a half-duplex channel. It can save frequency-band or a channel comparing with GBN ARQ strategy. Analysis is carried out about performance of this system. The result showed that a error rate of the system is similar to a error rate of SW or GBN ARQ strategy, that its throughput is much higher than that of SW ARQ strategy and similar to a throughput of GBN ARQ strategy. The system has excellent performance and practical value.
