提出了两种零相关区非周期互补序列集的构造方法。基于非周期互补序列(ACS)集和正交矩阵,利用级联运算构造了1个ZACS集。如果原ACS集能达到理论界,则所得集的参数是最优的。在构造2中,根据ZCS的不同设置方法,给出了两类基于两个正交矩阵的ZACS集,并且ZCZ的长度可以灵活选择。此外,与现有文献相比,这两个正交矩阵的阶可以不同。在这项研究中提出的ZACS集在多载波码分多址系统的实际利益。
Two constructions of zero correlation zone (ZCZ) aperiodic complementary sequence (ZACS) sets are presented. Based on aperiodic complementary sequence (ACS) sets and orthogonal matrices, construction 1 proposed ZACS sets by utilising cascade operation. Also, the parameters of the resulting sets are optimal if the original ACS sets can achieve the theoretical bound. In construction 2, according to different setting methods of ζ , two classes of ZACS sets are presented based on two orthogonal matrices, and the length of ZCZ can be chosen flexibly. Furthermore, compared with the existing references, the order of the two orthogonal matrices can be different. The ZACS sets presented in this study are of practical interest in multi-carriers code division multiple access systems.
