| 摘 要： | 介绍了一种有效的字节式单向错误纠错码及其编码和译码算法。从对校验位数下限值的讨论可以看出,这里介绍的码优于字节式对称错误纠错码,并且近似最优。本文还介绍了字节式非对称错误纠错码。

| Abstract: | An effective unidirectional byte error correcting code and its encoding/decoding algorithms are introduced in the paper. From the discussion about the lower limit of check digits.it can be seen that the unidirectional byte error correction code described here is superior over symmetric byte error correcting codes and is approximately the optimal one. Asymmetric byte error correcting codes are also described. |
