摘要
针对二元互补序列的构造问题,提出了一种直接构造方法——分圆类法.该方法利用"分圆类"原理直接构造出一类新定义的区组设计——互补差集偶,通过互补差集偶与二元互补序列的等价关系,构造出一类新的具有很好的"0"、"1"平衡性和好的自相关度的二元互补序列.使二元互补序列的构造理论得到了发展,能更好地满足实际工程的需要.
A direct design method of the complementary binary sequence is presented.A new block design（complementary difference set pairs） is defined,which is constructed based on the cyclotomic class.A new complementary binary sequence is given,taking advantage of the equivalence relation between difference set and sequence.Specially,any one of the new binary sequences has optimum balance among 0 and 1.The method proposed in this paper has wider existence space,which can satisfy the requirements of engineering applications.
