摘　　要：该文给出一类相互正交的二元零相关区序列集构造法。基于二元正交矩阵,首先构造得到了一类相互正交的非周期互补序列集,进而构造了相互正交的二元零相关区序列集,每个序列集参数都是最佳的。同已有方法相比,该文方法能生成更多的相互正交的二元零相关区序列集,解决了集合数目大于2且相互正交的最佳二元零相关区序列集构造问题,可以为准同步码分多址系统提供更多的序列。A class of mutually orthogonal binary Zero Correlation Zone （ZCZ） sequence sets are constructed, Based on binary orthogonal matrices, numbers of mutually orthogonal aperiodic complementary sequence sets are constructed at first, then mutually orthogonal ZCZ sequence sets are obtained from these aperiodic complementary sequence sets. Each ZCZ sequence set is an optimal binary ZCZ sequence set. Compared with existing methods, the presented construction produces more mutually orthogonal ZCZ sequence sets. As a result, the problem of constructing more than two optimal mutually orthogonal sets of binary ZCZ sequences is sloved by the presented approach and more sequences are produced for Quasi-Synchronous Code Division Multiple Access （QS-CDMA） systems.
