摘要
由于TD-SCDMA系统采用了智能天线和上行同步等关键技术,采用单基站实现用户的定位,节约无线资源,便成为了新的研究亮点。文章在对现行TD-SCDMA系统单基站定位技术进行分析的基础上,提出了一种新的联合参数估计的单基站定位法,仿真表明,该方法比现行方法能获得更好的定位效果。
TD-SCDMA system, owing to its smart antenna, uplink synchronization and other key technologies has unique advantage in wireless location. In this paper, several normal location algorithms in TD-SCDMA are analyzed. Based on some evolutions of these algorithms, a new single base-station location algorithm with joint parameters estimation is proposed. Its excellent performance is verified by a series of simulation analysis and comparison.
