关于线性码的理想

On the ideal associated to a linear code

Irene Márquez-Corbella, Edgar Martínez-Moro, Emilio Suárez-Canedo

摘要:

本文旨在探索线性码的代数结构和完整的解码过程之间的桥梁。为此,我们将特定的二项式理想$I_+(\mathcal C)$与任意线性码相关联。在这种理想的相对于度相容的排序的减少的格罗布纳基中涉及的二项式诱导唯一定义的测试集的代码,这允许描述的汉明度量解码过程。此外,在$I_+(\mathcal C)$的Graver基中所涉及的二项式提供了一个通用的测试集,该测试集原来是包含代码的最小支持集的码字的集合。

英文摘要:

This article aims to explore the bridge between the algebraic structure of a linear code and the complete decoding process. To this end, we associate a specific binomial ideal $I_+(\mathcal C)$ to an arbitrary linear code. The binomials involved in the reduced Gröbner basis of such an ideal relative to a degree-compatible ordering induce a uniquely defined test-set for the code, and this allows the description of a Hamming metric decoding procedure. Moreover, the binomials involved in the Graver basis of $I_+(\mathcal C)$ provide a universal test-set which turns out to be a set containing the set of codewords of minimal support of the code.
