摘　　要：TD-SCDMA系统主要采用上行同步和智能天线技术,使用单个服务基站实现对UE的DOA-TOA定位,克服了传统定位方法的缺点。主要对TD-SCDMA系统DOA-TOA定位关键技术进行分析和研究。分析TD-SCDMA系统DOA-TOA定位基本原理和实现流程,重点研究物理层信息帧结构、智能天线技术和上行同步等DOA-TOA定位关键技术,最后研究了DOA-TOA定位方法,并对不同环境下其定位误差性能进行了仿真分析。TD-SCDMA system with the techniques of uplink synchronization and smart antenna can realize the DOA-TOA positioning of the UE by a single serving base station,and overcome the shortcomings of the traditional positioning methods. The DOA-TOA positioning techniques of TD-SCDMA system are analyzed and researched in this paper. The basic positioning princi-ple and procedure of DOA-TOA positioning of TD-SCDMA system. An intensive study of the key technologies of DOA-TOA loca-tion in TD-SCDMA system is made,such as data frame structure of physical layer,uplink synchronization,smart antenna and so on. The DOA-TOA positioning method is researched. Simulation analysis of the positioning error was performed in different en-vironments.
