摘要
为了提供数量更多且具有良好相关性的序列,在几乎最佳自相关序列偶的基础上,提出了一种新的二元序列族——几乎最佳周期互补二元序列偶族(APCSPF)。研究了APCSPF的性质,用Fourier变换对APCSPF进行了谱分析,并从这方面得到了APCSPF存在的必要条件。最后给出了一种基于特殊阵列构造APCSPF的方法。
The concept of almost perfect autocorrelation sequence pairs is presented, and the theory of families of almost perfect periodic complementary binary sequence pairs (APCSPF) is given on the basis of the almost perfect autocorrelation sequence pairs. Some characteristics of APCSPF are discussed. The Fourier spectrum characteristics of APCSPF are studied, and the necessary conditions for the existence of APCSPF are given. The method for constructing an APCSPF is given and proved.
