几种最优秩度量码的编译码

Encoding and Decoding of Several Optimal Rank Metric Codes

Wrya K. Kadir, Chunlei Li, Ferdinando Zullo

摘要:

本文给出了几类最优秩度量码的编码和译码算法,它们的码是对称矩阵、交错矩阵和厄米特矩阵的限制形式。首先,我们证明了求值编码是这些代码的正确选择,然后我们为每个家族提供了简单的可逆编码方法。随后描述了用于码的唯一解码算法。解码算法是基于内插的,并且可以在多项式时间内唯一地校正具有高达$\lfloor(d-1)/2\rfloor$的秩的每个码的错误,其中$d$是码的最小距离。

英文摘要:

This paper presents encoding and decoding algorithms for several families of optimal rank metric codes whose codes are in restricted forms of symmetric, alternating and Hermitian matrices. First, we show the evaluation encoding is the right choice for these codes and then we provide easily reversible encoding methods for each family. Later unique decoding algorithms for the codes are described. The decoding algorithms are interpolation-based and can uniquely correct errors for each code with rank up to $\lfloor(d-1)/2\rfloor$ in polynomial-time, where $d$ is the minimum distance of the code.
