摘要

基于组合设计理论，对周期为N≡1（mod 4）的平衡最优几乎二元序列对的构造方法进行了研究。根据（几乎）二元序列对的不同组合，得出了最大互相关值分别为θ

=1，2，3，以此θ

值为前提，推导得出 3 种情况的自相关理论界，并生成了4类满足互相关值和自相关理论界下界值的平衡（几乎）最优几乎二元序列对。所提构造方法扩展了互相关值的取值范围并进一步降低了最优二元序列对的互相关值，且序列长度参数 f 可选择任意整数，丰富了最优二元序列对的存在空间。

Abstract

Based on the combinatorial design theory， the constructions of balanced optimal almost binary sequence pairs of period N≡1（mod 4）were researched.The maximal cross-correlation values θ

were obtained by different combinations of （almost） binary sequence pairs.Furthermore， three new bounds on the autocorrelation values under the precondition of the value of θ

=1，2，3 were presented individually.Meanwhile，four types of balanced（almost）optimal almost binary sequence pairs were generated， which satisfied the cross-correlation values and autocorrelation theory bounds.Through the constructions， the range of the cross-correlation values is expanded and the cross-correlation value of the optimal binary sequence pairs is further reduced.More than odd， the value of sequence length parameter f can be any integer， which enriches the existence space of the optimal binary sequence pair.
