关于某些三元LCD码

On Some Ternary LCD Codes

Nitin S. Darkunde, Arunkumar R. Patil

摘要:

本文的主要目的是研究$LCD$码。具有互补对偶的线性码($LCD$)是那些与其对偶码具有交集的码,如$\{0\}$。本文给出了$LCD$码的重要特征之一的Massey定理\cite{8}的另一种证明。令$LCD[n,k]_3$表示$[n,k,d]$三进制$LCD$码中$d$的可能值的最大值。在\cite{4}中,作者给出了$LCD[n,k]_2$的上界,并将这个结果推广到了$LCD[n,k]_q$,推广到了任意的$q$,其中$q$是某个素数幂.我们将讨论当$q=3$达到这个界限时的情况。

英文摘要:

The main aim of this paper is to study $LCD$ codes. Linear code with complementary dual($LCD$) are those codes which have their intersection with their dual code as $\{0\}$. In this paper we will give rather alternative proof of Massey's theorem\cite{8}, which is one of the most important characterization of $LCD$ codes. Let $LCD[n,k]_3$ denote the maximum of possible values of $d$ among $[n,k,d]$ ternary $LCD$ codes. In \cite{4}, authors have given upper bound on $LCD[n,k]_2$ and extended this result for $LCD[n,k]_q$, for any $q$, where $q$ is some prime power. We will discuss cases when this bound is attained for $q=3$.
