| 摘 要： | 给出了构造１－ｌＵＢＥＣ／ＡＵＥＤ（单个单向突发错误纠正／全部单向错误检测）码的充分必要条件和建议的１－ｌＵＢＥＣ／ＡＵＥＤ码校验位的下限；将纠单个突发错误Ｆｉｒｅ码进行扩展，得到了扩展Ｆｉｒｅ１－ｌＵＢＥＣ／ＡＵＥＤ码；证明了扩展Ｆｉｒｅ码为无序码和１－ｌＵＢＥＣ／ＡＵＥＤ码；最后给出了基于移位寄存器实现扩展Ｆｉｒｅ码的编－译码框图。在纠单向突发错误和检单向错误时，扩展Ｆｉｒｅ码具有更高的译码效率和信息率。

| Abstract: | The necessary and sufficient conditions for the l-lUBEC/AUED (single l length Unidirectional Burst Error-Correcting/All Unidirectional Error Detecting) codes and the lower bound of the check bits of the proposed codes are presented. The extended Fire codes,which have been proved to be unordered and l-lUBEC/AUED, are described, and the encoding/decoding diagrams to realize them are given. |
