叙述常用控制传输错误的方法及特点。针对短波信道的特点，提出在现有短波教传机所具有的FEC功能的基础上增加由计算机完成的ARQ功能的设计及实现方法．进—步改善了短波信道传输数据的质量，以适应某些低误码率数据传输的需要．
Describes the commonly used methods and features to control transmission errors. In view of the characteristics of shortwave channel, this paper proposes to increase the design and implementation of the ARQ function completed by the computer based on the FEC function of the existing shortwave teaching machine. Further improve the quality of short-wave channel data transmission to meet the needs of some low bit error rate data transmission.
