Hai Liu, Chengju Li, Haifeng Qian

摘要:

二元二元码是循环码的一个有趣的子类,因为它们具有很大的维数,并且它们的最小距离可能有一个平方根界。本文提出了几类长度为$2^m-1$的二元码,并利用循环码的BCH界给出了它们的最小距离的一些下界,部分地解决了\cite{LLD}中提出的一个公开问题.结果表明,它们的最小距离的下界接近平方根界。此外,这些二元码的对偶码和扩展码的参数进行了研究。

英文摘要:

Binary duadic codes are an interesting subclass of cyclic codes since they have large dimensions and their minimum distances may have a square-root bound. In this paper, we present several families of binary duadic codes of length $2^m-1$ and develop some lower bounds on their minimum distances by using the BCH bound on cyclic codes, which partially solves one case of the open problem proposed in \cite{LLD}. It is shown that the lower bounds on their minimum distances are close to the square root bound. Moreover, the parameters of the dual and extended codes of these binary duadic codes are investigated.
