摘　　要：提出了一种零相关区(ZCZ)周期互补序列偶集的交织构造方法.在互补序列偶集的基础上,通过选取合适的移位序列与正交矩阵,构造了具有更多序列偶数和灵活零相关区的ZCZ周期互补序列偶集.该方法结合了序列偶相关的思想,进一步扩展了扩频序列的可选空间.由于ZCZ互补序列集可以看做ZCZ互补序列偶集的特例,因此这种方法也适用于ZCZ周期互补序列集的构造,在扩频序列的设计中具有良好的应用前景.A construction method of zero correlation zone （ZCZ） periodic complementary sequence pairs sets based on interleaving technique is proposed. On the basis of the complementary sequence pair set, ZCZ periodic complementary sequence pairs sets with large family size and flexible zero correlation zone are constructed by appropriate shift sequences and orthogonal matrix. This method expands the existence space of the spread sequence by the idea of sequence pait correlation. Because ZCZ complementary sequences sets can be viewed as special case of ZCZ complementary sequence pairs sets, the method can also be used to construct ZCZ complementary sequences set. It has good application prospect in the design of spread sequence.
