We analyse the causes of data error during data transmission, compare several error-controlling codes with each other, and point out error-controlling developing trend. 摘要分析了数据传输差错产生的原因,比较了几种差错控制编码,最后指出了差错控制未来的研究方向。
The transmission errors and artificial factors lead to the nonstandard contents of telegraphs, which make the difficulties for the computer to process. 由于传输差错及人为因素引起了报文的非标准化,计算机自动处理困难。
