中文摘要：

该文给出一类零相关区高斯整数序列的直接构造法。该方法基于差集,利用移位序列得到一类零相关区高斯整数序列集,并且序列集的零相关区长度以及元素取值可灵活设定。由于差集的研究成果非常丰富,因此该方法可以为CDMA通信系统提供大量零相关区高斯整数序列集。

英文摘要：

A unified construction of Guassian integer sequence sets with Zero Correlation Zone （ZCZ） is presented. Based on difference sets, optimal or almost optimal ZCZ Gaussian integer sequence sets are constructed using shift sequences, whose ZCZ length and alphabets can be flexibly chosen. Since the study of difference sets has achieved abundant accomplishment, then the presented method will produce an abundance of ZCZ Gaussian integer sequence sets for CDMA systems.
