arq automatic repeat request

基本解釋

The first is the forward error control (FEC) and the second is the automatic-repeat-request (ARQ).
通信系統(tǒng)中的差錯控制方法基本可分為兩大類，即前向糾錯編碼（FEC）和自動重傳請求（ARQ）。
The undetected error probability of block cedes is an important parameter in automatic repeat request (ARQ) systems.
分組碼的未檢概率在ARQ體制中占有重要的地位。
Automatic Repeat-Request (ARQ) has been used widely for high reliability and convenience in implementation. But its low performance is shown When channel is in noisy state.
自動重發(fā)差錯控制方式由于可靠性高，實現簡單得到廣泛應用，但在信道干擾較強時效率較低。
