Z_{2k} -线性码的拟线性结构

Propelinear structure of Z_{2k}-linear codes

J. Borges, C. Fernandez-Cordoba, J. Rifa

摘要:

设C是$\Z_{2k}^n$的加法子群,对任意$k\geq 1$ .我们定义了一个Gray映射$Φ:\Z_{2k}^n \longrightarrow \Z_2^{kn}$,使得$Φ(\codi)$是一个二进制的proplelinear码,因此是一个Hamming相容的群码.此外,$Φ$是唯一的格雷映射,使得$Φ(C)$是汉明兼容的群码。利用这个Gray映射,我们讨论了1-完美二元混合群码的不存在性.

英文摘要:

Let C be an additive subgroup of $\Z_{2k}^n$ for any $k\geq 1$. We define a Gray map $Φ:\Z_{2k}^n \longrightarrow \Z_2^{kn}$ such that $Φ(\codi)$ is a binary propelinear code and, hence, a Hamming-compatible group code. Moreover, $Φ$ is the unique Gray map such that $Φ(C)$ is Hamming-compatible group code. Using this Gray map we discuss about the nonexistence of 1-perfect binary mixed group code.
