秩度量覆盖码的界

Bounds on Covering Codes with the Rank Metric

Maximilien Gadouleau, Zhiyuan Yan

摘要:

本文研究了秩度量空间的几何性质和秩度量码的覆盖性质。首先建立了两个秩半径球相交的解析表达式,然后导出了多个秩半径球并的体积的上界。利用这些几何性质,我们推导出一个给定的秩覆盖半径的代码的最小基数的上限和下限。本文给出的秩度量码的几何性质和界对于秩度量码的设计、译码和性能分析具有重要意义。

英文摘要:

In this paper, we investigate geometrical properties of the rank metric space and covering properties of rank metric codes. We first establish an analytical expression for the intersection of two balls with rank radii, and then derive an upper bound on the volume of the union of multiple balls with rank radii. Using these geometrical properties, we derive both upper and lower bounds on the minimum cardinality of a code with a given rank covering radius. The geometrical properties and bounds proposed in this paper are significant to the design, decoding, and performance analysis of rank metric codes.
