摘要:

提出了一种新的具有良好周期相关特性的离散信号,即二值自相关二进阵列偶,给出了它的定义,讨论了它的变换性质和Fourier频谱特性,为了缩小搜索范围,提高计算机搜索效率,研究给出了一些二值自相关二进阵列偶存在的必要条件,并给出了二值自相关二进阵列偶与二值自相关二进序列偶的折叠构造方法。

Abstract:

A new kind of discrete signal with good periodic correlation function is proposed. It is binary array pairs with two-level autocorrelation. The definition of binary array pairs with two-level autocorrelation is presented. Its transformation properties and Fourier spectrum characters are discussed. To reduce the searching range and improve the searching efficiency of binary array pairs with two-level autocorrelation, its existence conditions are studied. And folding construction between binary array pairs with two-level autocorrelation and binary sequence pairs with two-level autocorrelation is given out.

Key words: array pairs, periodic correlation, sequence design, signal theory, information theory
