具有秩度量的码的性质

Properties of Codes with the Rank Metric

Maximilien Gadouleau, Zhiyuan Yan

摘要:

本文研究了秩度量码的一般性质,特别是最大秩距离码的性质。对于具有秩度量的码,我们首先建立Gilbert界和球填充界,然后得到这两个界和Singleton界的渐近形式。基于渐近界,我们观察到渐近Gilbert-Varsharmov界被MRD码超过,球填充界不能达到。我们还建立了极大码的秩覆盖半径的界,证明了所有的MRD码都是极大码,并且所有已知的MRD码都达到了最大秩覆盖半径。

英文摘要:

In this paper, we study properties of rank metric codes in general and maximum rank distance (MRD) codes in particular. For codes with the rank metric, we first establish Gilbert and sphere-packing bounds, and then obtain the asymptotic forms of these two bounds and the Singleton bound. Based on the asymptotic bounds, we observe that asymptotically Gilbert-Varsharmov bound is exceeded by MRD codes and sphere-packing bound cannot be attained. We also establish bounds on the rank covering radius of maximal codes, and show that all MRD codes are maximal codes and all the MRD codes known so far achieve the maximum rank covering radius.
