该文给出了四元低相关区序列集的交织构造法。这类方法首先构造满足一定条件的四元基序列集，进而交织得到一类四元 LCZ 序列集。基于目前已有的二元基序列集给出了几种满足条件的四元基序列集，进而利用交织法得到了新的具有良好参数四元 LCZ 序列集。本文方法可以为准同步 CDMA 系统提供更多的四元 LCZ 序列集。

In this paper ,the construction of low correlation zone (LCZ) sequence sets by using the interleaved technique is proposed .A quaternary sequence set that satisfies conditions is constructed and then a quaternary LCZ sequence set is constructed based on the quaternary set and the interleaving technique .Numbers of quaternary component sequences are presented based on the known binary component .Different quaternary LCZ sequence sets can be obtained by these component sequence sets .Therefore , quaternary LCZ sequence sets proposed in this paper can be used in QS-CDMA systems to support more users .
