摘要:

既不等价于广义里德-所罗门(GRS)码的最大距离可分(MDS)码(非GRS MDS码)和近MDS(NMDS)码在通信和存储系统中都有良好的应用。本文引入并研究了一族新的线性码,涉及它们的参数、重量分布和自正交性质。我们证明这类码要么是非GRS MDS码,要么是NMDS码,因此它们可以尽可能多地产生所需的码。我们还借助某些子集和问题的解,完全确定了它们的重量分布。刻画了这类码自正交的充分必要条件。基于这一条件,我们进一步推断这类线性码中不存在自对偶码,并明确构造了两类新的几乎自对偶码。

英文摘要:

Both maximum distance separable (MDS) codes that are not equivalent to generalized Reed-Solomon (GRS) codes (non-GRS MDS codes) and near MDS (NMDS) codes have nice applications in communication and storage systems. In this paper, we introduce and study a new family of linear codes involving their parameters, weight distributions, and self-orthogonal properties. We prove that such codes are either non-GRS MDS codes or NMDS codes, and hence, they can produce as many of the desired codes as possible. We also completely determine their weight distributions with the help of the solutions to some subset sum problems. A sufficient and necessary condition for such codes to be self-orthogonal is characterized. Based on this condition, we further deduce that there are no self-dual codes in this class of linear codes and explicitly construct two new classes of almost self-dual codes.
