几乎最佳自相关序列偶

Almost Perfect Autocorrelation Sequence Pairs

提出几乎最佳自相关序列偶的概念 ,定义序列的一些变换形式 ,研究几乎最佳自相关序列偶的性质、存在的必要条件。运用以上得到的这些结果 ,可以使几乎最佳自相关序列偶的搜索范围大大缩小 ,提高了计算机对几乎最佳自相关序列偶搜索的效率 ,运用这些结果 ,同时也可以用已知的几乎最佳自相关序列偶构造出同长度的这种序列偶。

The concept of almost perfect autocorrelation sequen ce pairs is given.Some characters of the sequence pairs are discussed,and the ne cessary existent conditions of the sequence pairs are given.By use of the charac ters and the necessary condition of existence,the scope of searching the almost perfect autocorrelation sequence pairs is reduced.The Almost perfect autocorrela tion sequence pair that is of the same length as a known sequence pair can be constructed by using the characters and the necessary condition of existence.
