中文摘要： 随着人们对无线通信网络系统业务需求的多样性、稳定性、安全性以及服务质量的要求日益提高，序列因其易实现、高速、稳定等特点，在无线通信系统中得到了广泛应用。在实际通信系统中，准同步码分多址(CDMA)通信系统倍受关注，且针对准同步CDMA通信系统的扩频序列- - 零相关区(Zero Correlation Zone)序列的研究已取得了丰硕的成果。而非对称零相关区序列集总是比传统的零相关区序列集具有更大的零相关区宽度，更易实现无共道干扰的准同步CDMA扩频通信系统。本课题主要研究非对称零相关区序列集的理论体系和新的构造方法：1. 借鉴传统零相关区序列集的理论，研究非对称零相关区序列集的理论；2. 基于交织技术，研究非对称零相关区序列集设计；3. 基于非对称零相关区序列集的交织构造，研究传统零相关区序列集与非对称零相关区序列集间的映射关系。

英文摘要： With the daily growth of demands on variety, stability, security and quality of wireless network services, sequences have been widely used in wireless communication systems because of its ease realized, high-speed, stability and so on. In real communication system, much attention have been paid on quasi-synchronous Code Division Multiple Access (CDMA) communication system have been researched. Meanwhile, spreading sequence with Zero Correlation Zone (ZCZ) aiming at quasi-synchronous CDMA system, huge fruits has been achieved so far. Moreover, comparing to conventional ZCZ sequence sets, asymmetric ZCZ sequence sets always have larger ZCZ width and more easily provide quasi-synchronous CDMA communication without co-channel interference. In this project, we mainly research the theory architecture and new methods of design asymmetric ZCZ sequence sets: 1. Referring to conventional theories on ZCZ sequence sets, research theories of asymmetric ZCZ sequence sets; 2. Based on interleaved technique, research design of asymmetric ZCZ sequence sets; 3. Based on interleaved construction of asymmetric ZCZ sequence sets, research the mapping relationship between conventional ZCZ sequence sets and asymmetric ZCZ sequence sets.
