关于Reed-Muller码的注记

Notes on Reed-Muller Codes

Yanling Chen, Han Vinck

摘要:

本文研究了Reed-Muller(RM)码。对于一阶RM码,我们证明了它是唯一的,即任何具有相同长度、维数和最小距离的线性码都是一阶RM码;对于二阶RM码,当m为偶数时,我们给出了一个构造性的线性子码族.这是MacWilliams和Sloane的编码书中第15章推论17的扩展。此外,我们证明了长度<= 256的指定子码的最小距离等于所有长度和维数相同的线性码的上界或最佳已知下界。作为另一个有趣的结果,我们得到了满秩辛矩阵的可加交换群。

英文摘要:

In this paper, we consider the Reed-Muller (RM) codes. For the first order RM code, we prove that it is unique in the sense that any linear code with the same length, dimension and minimum distance must be the first order RM code; For the second order RM code, we give a constructive linear sub-code family for the case when m is even. This is an extension of Corollary 17 of Ch. 15 in the coding book by MacWilliams and Sloane. Furthermore, we show that the specified sub-codes of length <= 256 have minimum distance equal to the upper bound or the best known lower bound for all linear codes of the same length and dimension. As another interesting result, we derive an additive commutative group of the symplectic matrices with full rank.
