摘要
首先提出D—最佳自相关序列偶的概念 ,然后在此基础上得出了类最佳自相关序列偶的定义。根据对序列一些变换进行的定义 ,研究了类最佳自相关序列偶的性质、存在的必要条件 ,运用这些性质和存在必要条件可以使类最佳自相关序列偶的搜索范围大大缩小 ,提高了对类最佳自相关序列偶搜索效率 。
The concept of D-perfect autocorrelation sequences is prese nted, and t he theory of almost perfect autocorrelation sequence pairs is given on the basis of the D-perfect autocorrelation sequences. Some characters of the sequences ar e discussed, and the necessary conditions of existence are given. By using chara cters and the necessary condition of existence, the scope of searching the almos t perfect autocorrelation sequence pairs is reduced.
