零相关区屏蔽四元周期互补序列偶集设计研究

摘要

A design method of Zero Correlation Zone (ZCZ) punctured quaternary periodic complementary sequence pairs set is proposed. Based on perfect punctured binary sequences pairs and orthogonal matrix, ZCZ punctured sequence pairs sets can be constructed. Then, by interleaving iteration technique ZCZ punctured periodic complementary sequence pairs sets are obtained. Finally, ZCZ punctured quaternary periodic complementary sequence pairs sets are constructed using novel inverse Gray mapping. The results reach the theoretical bounds and further expand the selectable space of the spread spectrum sequences.%该文提出一种零相关区(ZCZ)屏蔽四元周期互补序列偶集的设计方法。基于最佳二元屏蔽序列偶和正交矩阵构成ZCZ屏蔽序列偶集，经过交织迭代得到ZCZ屏蔽周期互补序列偶集，进而利用新型逆Gray映射构造了ZCZ屏蔽四元周期互补序列偶集。结果达到理论界限，进一步拓展了扩频序列的可选空间。
