摘要
Cadic et al.(2001)和carach et al.(1999,2000)提出了一种新的利用短基码和置换的分组码编码构造方案，该方案能够构造二进制自对偶码。该方案可实现双平衡。假设基码是双偶自对偶码，并且排列的数目是偶的(例如:奇怪的)。我们研究了基码为[8,4,4]扩展汉明的特殊情况。在这种特殊情况下，构造了一个新的[88,44,16]极值双偶自对偶码，并给出了5个[32,16,8]极值双偶自对偶码的一个新的统一构造。
A new coding construction scheme of block codes using short base codes and permutations that enables the construction of binary self-dual codes is presented in Cadic et al. (2001) and Carlach et al. (1999, 2000). The scheme leads to doubly-even (resp,. singly-even) self-dual codes provided the base code is a doubly-even self-dual code and the number of permutations is even (resp., odd). We study the particular case where the base code is the [8, 4, 4] extended Hamming. In this special case, we construct a new [88, 44, 16] extremal doubly-even self-dual code and we give a new unified construction of the five [32, 16, 8] extremal doubly-even self-dual codes.
