Hermitian Self-Dual扩展Duadic码的长度

The lengths of Hermitian Self-Dual Extended Duadic Codes

Lilibeth Dicuangco, Pieter Moree, Patrick Sole

摘要:

Duadic码是一类循环码,它将二次剩余码从素数长度推广到复合长度。对于每一个素数幂q,我们刻画整数n,使得在具有q^2个元素的有限域上,存在长度为n的具有厄米特自对偶奇偶校验扩展的二元码。我们推导出使用解析数论渐近估计的数量,这样的n以及长度的数量,其中二元码存在。

英文摘要:

Duadic codes are a class of cyclic codes that generalizes quadratic residue codes from prime to composite lengths. For every prime power q, we characterize the integers n such that over the finite field with q^2 elements there is a duadic code of length n having an Hermitian self-dual parity-check extension. We derive using analytic number theory asymptotic estimates for the number of such n as well as for the number of lengths for which duadic codes exist.
