摘要

基于中国剩余定理和四阶分圆类，对周期为N=2q(q为奇素数)的几乎四进制序列的构造方法进行了研究。根据序列y的y(0)和y(q)2个位置含0的个数对序列进行分类，构造得到了旁瓣值分别为{0

-2}、{0

-2

-2i

2i}，且具有好的平衡性的3类理想几乎四进制序列。所提构造方法得到的序列具有良好的自相关性和平衡性，扩大了现有理想平衡四进制序列的存在范围，为实际应用提供了更多性能优良的序列。

Abstract

Based on the Chinese remainder theorem and cyclotomic classes of order 4

the constructions of almost quaternary sequences with period N=2q (where q is an odd prime) was studied.According to the number of “0” in the two positions y(0) and y(q)

three types of optimal almost quaternary sequences with optimal balance property and out-of-phase autocorrelation values as{0

-2}

-2} and {0

-2

-2i

2i} were constructed respectively.Through these constructions

all the almost quaternary sequences constructed are balanced and optimal.These constructed sequences extend the existence range of the balanced optimal quaternary sequences and provide more optimal sequences for practical applications.
