digital error-correction

基本解释

Forward-error correction (FEC) and automatic repeat-request (ARQ) are two kinds of error-control in digital communication system.
前向纠错（FEC）和自动重传请求（ARQ）是数字通信系统中常用的两种差错控制方式。
In chinese national standard for Digital Multimedia Terrestrial Broadcasting(DMB-T), QC irregular LDPC code is used as forward error correction coding.
在我国的数字电视广播地面传输标准DMB-T中，使用了准循环非规则LDPC码作为前向纠错编码。

In Chinese national standard for Digital Terrestrial Multimedia Broadcasting (DTMB), irregular Quasi Cyclic LDPC (QC- LDPC) code is used as core part of forward error correction coding.
在中国数字电视广播地面传输标准（DTMB）中，使用了非规则准循环LDPC码（QC-LDPC）作为前向纠错编码的核心部分。
