一致的标志代码

Consistent Flag Codes

Clementa Alonso-González, Miguel Ángel Navarro-Pérez

摘要:

本文研究了$\mathbb{F}_q^n$上的标志码,其中$\mathbb{F}_q$是具有$q$元素的有限域.特别注意的是一个标志代码和一个家庭的恒定尺寸的代码自然与它(投影代码)的参数和属性之间的连接。更准确地说,我们专注于一致的标志码,即标志码的距离和大小完全由其投影码决定。我们探讨了这个家庭的代码的一些方面,并提出了他们的例子,通过推广的概念,等距和向日葵子空间代码的标志代码设置。最后,我们提出了一个解码算法的一致性标志码,充分利用的一致性条件。

英文摘要:

In this paper we study flag codes on $\mathbb{F}_q^n$, being $\mathbb{F}_q$ the finite field with $q$ elements. Special attention is given to the connection between the parameters and properties of a flag code and the ones of a family of constant dimension codes naturally associated to it (the projected codes). More precisely, we focus on consistent flag codes, that is, flag codes whose distance and size are completely determined by their projected codes. We explore some aspects of this family of codes and present examples of them by generalizing the concepts of equidistant and sunflower subspace code to the flag codes setting. Finally, we present a decoding algorithm for consistent flag codes that fully exploits the consistency condition.
