AI总结:

本文研究子空间码的线性互补对,提出其特征化及存在性条件,并通过多种构造方法实现其应用,用于插入错误纠正。

摘要:

一个子空间码是向量空间F_q^n的非空子空间集合。一对线性码称为线性互补对(LCP)若其交集为平凡且维度和等于 ambient 空间维度。本文引入子空间码的LCP概念,首先提供子空间码构成LCP的特征化。进一步,基于子空间码上的补函数给出LCP存在的充分条件。此外,通过多种技术提供子空间码LCP的构造方法,并应用于插入错误纠正。

英文摘要:

A subspace code is a nonempty collection of subspaces of the vector space $\mathbb{F}_q^{n}$. A pair of linear codes is called a linear complementary pair (in short LCP) of codes if their intersection is trivial and the sum of their dimensions equals the dimension of the ambient space. In this paper, we introduce the concept of LCPs of subspace codes. We first provide a characterization of subspace codes that form an LCP. Furthermore, we present a sufficient condition for the existence of an LCP of subspace codes based on a complement function on a subspace code. In addition, we give several constructions of LCPs for subspace codes using various techniques and provide an application to insertion error correction.
