【摘要】 文中重点对在TD-SCDMA系统中,采用JADE-MUSIC算法联合提取TOA和AOA定位参数,实现单基站定位的技术进行了分析和研究。通过上行同步偏移参量获得TOA值,通过智能天线的DOA估计获得AOA值,实现TOA与AOA相结合的单站定位是现在比较盛行的方法。但这种方法受限于同步偏移参量的步进。针对此,对基于经典JADE-MUSIC谱估计算法的联合AOA和TOA参数提取的单站定位技术进行区域划分进行一定的研究。更多还原

【Abstract】 This paper focuses on using JADE-MUSIC algorithm to extract TOA and AOA location parameters, to located UE by a single base station technology in TD-SCDMA system. By extracting TOA and DOA from the offset parameters of uplink synchronization and the DOA estimation of the smart antenna separately, this mode could be implemented in TD-SCDMA system. However, it is limited to the steps of the offset parameters. As for this, a joint estimation algorithm based on classic JADE-MUSIC for location is discussed.更多还原
