含Gabidulin码的秩度量码的列表可译码性

On the list decodability of rank-metric codes containing Gabidulin codes

Paolo Santonastaso, Ferdinando Zullo

摘要:

Wachter-Zeh在[42]中以及后来与Raviv [31]一起证明,如果$τ$足够大,则对于任何半径$τ$,Gabidulin码都不能被有效地列表解码。此外,他们还证明了Gabidulin码的参数有无穷多个选择,无法有效地进行列表解码。随后,在[41]中,这些结果被推广到广义Gabidulin码族和进一步的MRD-码族。在本文中,我们提供的范围内的秩度量码的列表大小包含广义Gabidulin码,以确定是否存在一个多项式时间的列表解码算法。我们检测几个家庭的秩度量码包含一个广义Gabidulin码作为子码,不能有效地列表解码的任何半径足够大,不能有效地列表解码的秩度量码的家庭。这些结果表明,秩度量码是$\mathbb{F}_{q^m}$ -线性的或包含(幂)广义Gabidulin码不能有效地列表解码的大值的半径。

英文摘要:

Wachter-Zeh in [42], and later together with Raviv [31], proved that Gabidulin codes cannot be efficiently list decoded for any radius $τ$, providing that $τ$ is large enough. Also, they proved that there are infinitely many choices of the parameters for which Gabidulin codes cannot be efficiently list decoded at all. Subsequently, in [41] these results have been extended to the family of generalized Gabidulin codes and to further family of MRD-codes. In this paper, we provide bounds on the list size of rank-metric codes containing generalized Gabidulin codes in order to determine whether or not a polynomial-time list decoding algorithm exists. We detect several families of rank-metric codes containing a generalized Gabidulin code as subcode which cannot be efficiently list decoded for any radius large enough and families of rank-metric codes which cannot be efficiently list decoded. These results suggest that rank-metric codes which are $\mathbb{F}_{q^m}$-linear or that contains a (power of) generalized Gabidulin code cannot be efficiently list decoded for large values of the radius.
