Byte error correcting codes are demanded in byte-oriented systems such as main memory, data transfer path, etc.. In this paper a class of single byte error correcting double byte error detecting codes (Sb/EC Db/ED codes) generated by means of the recursive process is presented. If the byte length is b, the length of checking part of the code is m bytes, the length of information part of the code is k bytes, then the maximal code length will be n=m+k=2m-2...

Byte error correcting codes are demanded in byte-oriented systems such as main memory, data transfer path, etc.. In this paper a class of single byte error correcting double byte error detecting codes (Sb/EC Db/ED codes) generated by means of the recursive process is presented. If the byte length is b, the length of checking part of the code is m bytes, the length of information part of the code is k bytes, then the maximal code length will be n=m+k=2m-2 (2b-1+1) bytes. In case of b= 1, these codes are the same with the ordinary binary Hamming SBC DED codes. Furthermore, another class of Sb/EC Db/BD rotation codes is produced with a computer. The length of such a code is longer than that of the previous one as the length of the checking part is increased.

对于面向字节组织的系统,如存储器、数据传输通路等,为了提高系统可靠性,需要采用能校正字节错的纠错码。本文提出一种用递归方法形成的单字节错校正双字节错检测码(S_bEC/D_bED码)。设字节长度为b位,该代码的校验部分长度为m字节,信息部分长度为k字节,则最大代码长度为n=2~(m-2)(2~(b-1)+1)字节。在b=1的特殊情况下,即为一般二元海明SEC/DED码。此外,用计算机推导出一种S_bEC/D_bED旋转码,这种码随校验部分长度的增加,具有比前一种码更大的代码长度。

The BCH code is a widely used error——correcting code. Although it can correct a number of errors if necessary, its efficency is not very high. The generalized BCH code improves the function of the BCH code. In this paper, the concept of the generalized BCH code is introduced, and its capacity of error——correcting is discussed.

BCH码是一类有广泛应用的纠错码,它可以根据需要纠正多个差错,但效率不是很高。广义BCH码改进了BCH码的性能。本文引进了广义BCH码的概念,并且探讨了它的纠错能力。
