摘要
利用误差分析的方法探讨了影响无线网络定位精度的有关因素。其定位误差主要取决于网络中各信标台的几何分布,及各测量值的大小。仿真显示:不同的信标组合其定位误差不同,通过TOA定位算法的分析、仿真及总结,给出了影响定位精度因素及提高定位精度的方法,为移动台的定位方案的选取提供理论依据。
Based on the analysis of error, this article discusses the location precision of wireless network. Location error mostly lies on location of beacon station and data of measured. Emulations reveal difference of location error when we fit together data of different beacon station. Factors which affect precision of localization and improve precision are presented after we make analysis,emulation and summarization of TOA algorithm. These offer dependences for location scheme of mobile station.
