新的自对偶码族

New families of self-dual codes

Lin Sok

摘要:

在{ IEEE Transactions on信息论}中接受的题为“MDS自对偶码的显式构造”的最近论文中,doi:10.1109/TIT.2019.2954877,作者从亏格零代数几何(AG)码构造了MDS自对偶码族,其中使用两个除数$G$和$D=P_1+\cdots+P_n.$来定义长度为$n$的AG码。在本通信中,我们从AG码中探索更多的最优自对偶码族。利用亏格为零和亏格为一的曲线分别构造了一类新的具有奇特征的MDS自对偶码和几乎MDS自对偶码。利用高亏格的代数曲线构造了更多的自对偶码族。

英文摘要:

In the recent paper entitled "Explicit constructions of MDS self-dual codes" accepted in { IEEE Transactions on Information Theory}, doi: 10.1109/TIT.2019.2954877, the author has constructed families of MDS self-dual codes from genus zero algebraic geometry (AG) codes, where the AG codes of length $n$ were defined using two divisors $G$ and $D=P_1+\cdots+P_n.$ In the present correspondence, we explore more families of optimal self-dual codes from AG codes. New families of MDS self-dual codes with odd characteristics and those of almost MDS self-dual codes are constructed explicitly from genus zero and genus one curves, respectively. More families of self-dual codes are constructed from algebraic curves of higher genus.
