一类非二元Kasami循环码的$2$ -设计的无限族

Infinite families of $2$-designs from a class of non-binary Kasami cyclic codes

Rong Wang, Xiaoni Du, Cuiling Fan

摘要:

组合$t$ -设计在编码理论、密码学、通信和统计学等领域有着广泛的应用,因此多年来一直是一个重要的研究课题。编码理论和$t$ -设计之间的相互作用已经引起了这两个方向的大量关注。众所周知,任何有限域上的线性码都可以由$t$ -设计的关联矩阵导出,同时,码中所有固定权码字的支集也可以成立$t$ -设计。本文通过确定一类由非二元Kasami循环码导出的线性码的权重分布,从这类码中所有具有固定重量的码字的支持集得到了$2$ -设计的无限族,并明确地计算了它们的参数.

英文摘要:

Combinatorial $t$-designs have been an important research subject for many years, as they have wide applications in coding theory, cryptography, communications and statistics. The interplay between coding theory and $t$-designs has been attracted a lot of attention for both directions. It is well known that a linear code over any finite field can be derived from the incidence matrix of a $t$-design, meanwhile, that the supports of all codewords with a fixed weight in a code also may hold a $t$-design. In this paper, by determining the weight distribution of a class of linear codes derived from non-binary Kasami cyclic codes, we obtain infinite families of $2$-designs from the supports of all codewords with a fixed weight in these codes, and calculate their parameters explicitly.
