网络编码中的平面扩展标志码

Flag Codes from Planar Spreads in Network Coding

Clementa Alonso-González, Miguel Ángel Navarro-Pérez, Xaro Soler-Escrivà

摘要:

本文研究了一类由向量空间$\mathbb{F}_q^n$的嵌套子空间(标志)族给出的多重网络码,其中$q$是素幂,$\mathbb{F}_q$是$q$元素的有限域.特别地,我们关注具有最大最小距离的标志码(最佳距离标志码)。我们探索这些代码的存在,从蔓延,后者的良好性能的基础上。对于$n=2k$,我们表明,最佳的距离全标志码的最大尺寸正是那些可以从一个平面扩展。我们给出了一个精确的结构以及解码算法。

英文摘要:

In this paper we study a class of multishot network codes given by families of nested subspaces (flags) of a vector space $\mathbb{F}_q^n$, being $q$ a prime power and $\mathbb{F}_q$ the finite field of $q$ elements. In particular, we focus on flag codes having maximum minimum distance (optimum distance flag codes). We explore the existence of these codes from spreads, based on the good properties of the latter ones. For $n=2k$, we show that optimum distance full flag codes with the largest size are exactly those that can be constructed from a planar spread. We give a precise construction of them as well as a decoding algorithm.
