关于注入度量的射影空间码

Projective Space Codes for the Injection Metric

Azadeh Khaleghi, Frank R. Kschischang

摘要:

在随机线性网络编码中的错误控制的上下文中,构造包括有限域上的向量空间的子空间的良好分离的集合的代码是有用的。在本文中,使用的度量是所谓的“注入距离”,介绍了席尔瓦和Kschischang。Gilbert-Varshamov界的这种代码的推导。使用代码建设框架的Etzion和Silberstein,新的非常数维码构造,这些代码包含更多的码字比可比的代码设计的子空间度量。

英文摘要:

In the context of error control in random linear network coding, it is useful to construct codes that comprise well-separated collections of subspaces of a vector space over a finite field. In this paper, the metric used is the so-called "injection distance", introduced by Silva and Kschischang. A Gilbert-Varshamov bound for such codes is derived. Using the code-construction framework of Etzion and Silberstein, new non-constant-dimension codes are constructed; these codes contain more codewords than comparable codes designed for the subspace metric.
