In this paper, based on thecharacteristic of long round trip delay, an efficient ARQ protocol, which is suitable for half-duplex channels, is presented byremarkably shortening the responding time of each packet data.

- 本文針對水聲信道長(cháng)傳播時(shí)延這一特點(diǎn),利用擴頻通信技術(shù),將單個(gè)信道分成兩個(gè)子信道:一個(gè)用于前向信道(從發(fā)送方到接收方),另一個(gè)用于反向信道(從接收方到發(fā)送方),從而使得對每個(gè)分組數據的響應時(shí)間大大縮短,提出了一種有效的適合于半雙工特性的ARQ協(xié)議。
