有限链环上循环码的压缩

Contraction of Cyclic Codes Over Finite Chain Rings

Alexandre Fotue Tabue, Christophe Mouaha

摘要:

设$\texttt{R}$是一个可交换的有限链环,其不变量为$(q,s)$,$Γ(\texttt{R})$是$\texttt{R}.$的Teichmüller集。本文给出了长度为$\ell,$的循环$\texttt{R}$ -线性码的迹表示,当$\texttt{gcd}(\ell, q) = 1.$时,我们将证明某些长度为$u\ell$的循环$\texttt{R}$ -线性码的压缩是$γ$ -常循环$\texttt{R}$ -长度为$\ell,$的线性码,其中$γ\inΓ(\texttt{R})$和的乘法阶为$u.$

英文摘要:

Let $\texttt{R}$ be a commutative finite chain ring of invariants $(q,s)$ and $Γ(\texttt{R})$ the Teichmüller's set of $\texttt{R}.$ In this paper, the trace representation cyclic $\texttt{R}$-linear codes of length $\ell,$ is presented, when $\texttt{gcd}(\ell, q) = 1.$ We will show that the contractions of some cyclic $\texttt{R}$-linear codes of length $u\ell$ are $γ$-constacyclic $\texttt{R}$-linear codes of length $\ell,$ where $γ\inΓ(\texttt{R})$ and the multiplicative order of is $u.$
