线性秩度量码的最大码重

Maximum weight codewords of a linear rank metric code

Olga Polverino, Paolo Santonastaso, Ferdinando Zullo

摘要:

设$\mathcal{C}\subseteq \mathbb{F}_{q^m}^n$是维数为$k$的$\mathbb{F}_{q^m}$ -线性非退化秩度量码.本文研究了$\mathcal{C}$中具有最大权值的码字个数$M(\mathcal{C})$,即$\min\{m,n\}$的确定问题,并刻画了具有最大值和最小值的码字个数$M(\mathcal{C})$的特征.

英文摘要:

Let $\mathcal{C}\subseteq \mathbb{F}_{q^m}^n$ be an $\mathbb{F}_{q^m}$-linear non-degenerate rank metric code with dimension $k$. In this paper we investigate the problem of determining the number $M(\mathcal{C})$ of codewords in $\mathcal{C}$ with maximum weight, that is $\min\{m,n\}$, and to characterize those with the maximum and the minimum values of $M(\mathcal{C})$.
