准扭双权码的构造

Constructions of Quasi-Twisted Two-Weight Codes

Eric Z. Chen

摘要:

如果非零码字仅具有两个不同的权重w1和w2,则称代码为双权重。双权码与强正则图密切相关。在这篇论文中。证明了复合长度的常循环码可以用拟扭形式表示。基于这种变换,提出了一种新的准扭(QT)二重码的构造方法。发现了大量的QT二重码,并构造了一些新的码。

英文摘要:

A code is said to be two-weight if the non-zero codewords have only two different a weight w1 and w2. Two-weight codes are closely related to strongly regular graphs. In this paper. It is shown that a consta-cyclic code of composite length can be put in the quasi-twisted form. Based on this transformation, a new construction method of quasi-twisted (QT) two-weight codes is presented. A large amount of QT two-weight codes are found, and some new codes are also constructed.
