| 摘 要： | 在自动请求重发（ＡＲＱ）方案中，选择重发（ＳＲ）比等待重发（ＳＷ）和重返Ｎ－ＧＢＮ具有更高的传输效率，该效率是信道误码率、帧长及往返延时的函数。在任一给定的误码率情况下，可求得一种最佳帧长使传输效率达到最高。

| Abstract: | In the conventional ARQ scheme,theselective repeat(SR)provides a higher through-put than either the stop and wait(SW)or the go-back-N(GBN)ones,the throughput is afunction of the channel error rate,the frame size and the round trip delay.In a given channelerror rate,there is an optimal frame size which will give a maximum throughput.An adap-tive algorithm capable of automatically varying the frame size round its optimum value according to the channel error rate is proposed. |
