中文摘要: 序列设计是实现码分复用的重要手段,是码分多址通信的关键技术。适用于未来高速率、高频谱效率的准同步码分多址系统的序列设计研究成果还不多,远远不能满足实际需求。针对准同步码分多址系统,本项目研究一类具有高信息传输速率和高频谱效率并且同时能降低干扰的新型地址码。本项目围绕地址码的分析、设计、应用等问题展开以下工作: 研究高斯整数域上的完备序列、零相关区序列设计方法研究;研究具有灵活参数的零相关区周期互补序列集和零相关区非周期序列集设计方法研究;基于新型地址码,建立高速率、高频谱效率的码分多址系统模型,研究新型地址码在实际系统中的应用。本项目的研究在理论上将是对零相关区序列设计理论的一个重要补充,开辟零相关区序列设计新的研究方向。在工程实践上可以为高速率、高频谱效率准同步码分多址系统提供地址码,从而推动未来宽带移动通信系统与网络体系的发展。

英文摘要: Sequence design is an improtant way to realize code division multiplexing, and is a key technique in code-division multiple-access (CDMA) systems. The researches of sequence designing for high rate and high spectral efficiency QS-CDMA systems are somewhat few. This project studies a new kind of address codes with high rate and high spectral efficiency which can be potentially employed in quasi-synchronized CDMA communication systems to suppress interference. It focuses on the study of the analysis、the construction and the application of new class of access codes, which includes the study of constructions of perfect Gaussian integer sequences and ZCZ Gaussian integer sequence sets and the study of constructions of ZCZ complementary sequence sets with flexible parameters. It will finally establish a QS-CDMA system model with high rate and high spectral efficiency by applying the new access codes, and the properties of the model will be analyzed by computer simulation. In theory, this project will complete the ZCZ sequences theory. In application, this project will provide address codes for high rate and high spectral efficiency CDMA systems, which will be of great significance to the development of wide-band mobile communication network in the future.
