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
