描述了构造Z-互补序列集的方法。与那些以互补序列为核的构造不同，该构造是基于具有周期和非周期零相关区(PAZCZ)的序列。这些PAZCZ序列是么正序列，而不是互补序列。通过对PAZCZ序列进行交织迭代和正交矩阵展开，可以获得理想的二值零互相关区(ZCCZ)特性。与单值ZCCZ通常等于元素序列长度的Z-互补序列集相比，所提出的具有二值ZCCZ的Z-互补序列集具有更大的集合规模，从而可以支持更多的用户。
Methods of constructing Z-complementary sequence sets are described. Different from those constructions using complementary sequences as a kernel, the proposed constructions are based on sequences with periodic and aperiodic zero-correlation zone (PAZCZ). These PAZCZ sequences are unitary sequences, not complementary sequences. By means of interleaving iteration and orthogonal matrix expansion of PAZCZ sequences, desirable bivalued zero cross-correlation zone (ZCCZ) characteristics can be obtained. Compared with Z-complementary sequence sets with single value ZCCZ which is generally equal to the length of an element sequence, the proposed Z-complementary sequence sets with bivalued ZCCZ have larger set size and then can support more users.
