摘要
利用2阶分圆以及直积方法构造出几类几乎差集偶,通过几乎差集偶与三值自相关二进序列偶的等价关系,进而构造出几类新的三值自相关二进序列偶,为三值自相关二进序列偶的直接构造提供了新的数学方法.
Several classes of almost difference set pairs are given by means of 2-ordered eyelotomic classes and direct product. Then several classes of binary sequence pairs with three-level autocorrelation can be constructed by using the equivalence relation between almost difference set pairs and binary sequence pairs with three-level autocorrelation. The new mathmatical method for the direct construction of binary sequence pairs with three-level autocorrelation is provided.
