(2)《区组长度为5的正则循环填充》
摘要:给定正整数v,k,λ,满足v>k.设Zv表示模v的剩余类环,再设B={B1,B2…,Bt}为Zv上的一族k元
子集,其中Bi={bi1,6i2…,6ik),1≢i≢t,称为基区组.定义△(B)={bij-bis:1≢i≢t,j≠s,1≢j,s≢
k).如果△(B)覆盖Zv的非零剩余至多一次,则称B为一个阶为v,区组长度为k,指标λ=1的循环填充
(cyclicpacking),简记为CP(k,1,v).集合Zv\△(B)定义为该循环填充的差剩余(differenceleave),
简记为DL(B).如果DL(B)是Zv的一个g阶子群,则称B为g-正则的CP(k,1;v).如果1≢g≢k(k-1),则
一个g-正则的CP(k,1;v)是—个最优的CP(k,1;v).一个最优的CP(k,1;v)是一个长度为v,重量为k,自相
关和互相关特征λ=1的最优光正交码的组合刻画.g-正则的CP(k,1;v)不仅具有重要的理论意义,而且在
通信编码中有着很好的应用意义.关于g-正则的CP(k,1;v)的存在性问题得到了诸多学者的关注.(见文献
[1,2,3,4,5,6,7,8,9]).本文中,我们主要运用分圆类理论,通过直接构作及递归构作等方法得
到如下两个结果。定理2.9对任意的素数p=1(mod6),20-正则的CP(5,1;20p)存在.定理3.5设u是正
整数,其素因子p=1(mod6),则对于任意的非负整数α,存在最优的(20·3αu,5,1)-OOC.作者:杨晓

Abstract:
光正交码具有良好的光学相关特性,它特别适用于光纤信道上的码分多址系统.利用Weil定理给出了参
数为(15p,5,1)的最优光正交码的组合构作,其中p为模4余1且大于5的素数.由此,当正整数v的
质因子均为模4余1且大于5的素数时,(15v,5,1)最优光正交码可利用已知的递归构造方法得到.
