摘要
定位算法是无线定位技术研究的核心,其优劣将直接影响整个定位系统的性能。针对蜂窝网无线定位技术的特点,提出了一种基于坐标变换对TOA定位测量数据进行位置解算的方法,该方法通过对测量点的空间坐标变换,避免了位置解算过程中的方程线性化问题,减小了计算复杂度,并能大大提高位置解算的精度。实验结果表明,相对于泰勒级数展开法,有效地提高了系统定位性能。
The location algorithm is the core of wireless location technology research. Its quality would directly affect the performance of location system. In accordance with the feature of wireless location technology, based on coordinate transform principle, a method which is designed for position solution by using TOA measuring data is presented in this paper. By transform of spatial coordinar to location object, this method avoids the trouble of equation linearization, reduces calculation complexity, and greatly improves the precision of location estimation. Compared with the method of Expand to Taylor＇s Series, the simulation shows that this proposed method can effectively enhance performance of location system.
