完整关节重量计数器和self-dual代码的平均值

Average of complete joint weight enumerators and self-dual codes

Himadri Shekhar Chakraborty, Tsuyoshi Miezaki

摘要:

本文利用$n$的合成及其在码中的分布,给出了长度为$\mathbb{F}_{q}$和$\mathbb{Z}_{k}$上的两个线性码$n$的完全联合重量计数元的平均数的表示.我们还得到了$\mathbb{F}_{q}$和$\mathbb{Z}_{k}$上码的$g$ -倍完全联合重量计数元的平均值的一个推广.最后,计算一对III型(分别为10和20)的相交数的平均值。IV)型码,并求出了它的二阶矩。

英文摘要:

In this paper, we give a representation of the average of complete joint weight enumerators of two linear codes of length $n$ over $\mathbb{F}_{q}$ and $\mathbb{Z}_{k}$ in terms of the compositions of $n$ and their distributions in the codes. We also obtain a generalization of the representation for the average of $g$-fold complete joint weight enumerators of codes over $\mathbb{F}_{q}$ and $\mathbb{Z}_{k}$. Finally, the average of intersection numbers of a pair of Type III (resp. Type IV) codes, and its second moment are found.
