介绍了非周期性四相Z互补序列，其中包括作为特殊情况的常规互补序列。结果表明，非周期性四相Z互补对在Z互补对的数量和最大零相关区方面通常优于相同长度的二进制Z互补对。提出了四相序列初等变换和四相 Z 补序列集的初等运算的新概念。特别是，提出了用于分析与四相Z互补序列组相关的公式之间的关系以及描述该组的新方法。研究了零相关区为2、3、4的四相序列Z互补对的存在问题。给出了四相 Z 互补序列组及其配对的构造。
Aperiodic quadriphase Z-complementary sequences, which include the conventional complementary sequences as special cases, are introduced. It is shown that, the aperiodic quadriphase Z-complementary pairs are normally better than binary ones of the same length, in terms of the number of Z-complementary pairs, and the maximum zero correlation zone. New notions of elementary transformations on quadriphase sequences and elementary operations on sets of quadriphase Z-complementary sequences are presented. In particular, new methods for analyzing the relations among the formulas relative to sets of quadriphase Z-complementary sequences and for describing the sets are proposed. The existence problem of Z-complementary pairs of quadriphase sequences with zero correlation zone equal to 2, 3, and 4 is investigated. Constructions of sets of quadriphase Z-complementary sequences and their mates are given.
