Abstract: 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.
