本文叙述在汉字通信控制器中使用的按帧自动连续重发反馈纠错方式的基原本理.是根据在无线电报中广泛使用的按字符自动重发反馈(ARQ)的基础上提出来的. 关于纠错方式,可分成三大类:前向纠错方式、重发纠错方式和混合方式.本文只涉及重发纠错方式.重发纠错又分为:等候重发反馈和自动连续重反馈纠错方式.
This paper describes the basic principles of frame-by-frame automatic continuous retransmission feedback error correction used in Chinese communication controllers based on the character-based Automatic Retransmission (ARQ), which is widely used in radiotelegraphy. About error correction methods, can be divided into three categories: forward error correction, retransmission error correction and hybrid methods.This article only involves retransmission error correction.Re-error correction is divided into: waiting for retransmission feedback and automatic continuous Heavy feedback error correction.
