摘要
本文提出了一种利用最佳自相关序列偶、正交矩阵和交织技术构造具有一定序列偶数目和零相关区长度的ZCZ序列偶集的新方法。它不仅统一了三元、四相或多相ZCZ序列偶集的构造方法,而且由于ZCZ序列可以看作ZCZ序列偶的特例,因此这种方法也适用于ZCZ序列集的构造。这在QS-CDMA系统扩频序列的设计中有很好的应用前景。
A new construction method for ZCZ sequence pairs set is presented. Based on perfect autocorrelation sequence pair and orthogonal matrix, ZCZ sequence pairs set with certain family size and zero correlation zone can be constructed through interleaved technique. The proposed technique unified the construction methods of ternary, quadriphase or polyphase ZCZ sequence pairs sets. And since ZCZ sequence can be considered as the special case of ZCZ sequence pairs, it also fits to create ZCZ sequences set. It has good application foreground in spreading sequences design of QS-CDMA system.
