摘要
本文基于数据融合的基本原理,利用TOA和TDOA测量数据并结合先验信息进行数据融合,然后通过定义可信度函数构造了一种基于移动台位置的动态定位算法,进一步提高了对移动台(MS)定位估计的准确性。最后仿真结果表明:这种融合算法模型在保证决策可靠的前提下,能得到更准确可靠的移动台估计位置,从而有效提高了决策输出的定位精度。
A TOA/TDOA data fusion model with sector auxiliary information for cellular location is developed based on mathematical fusion. Through defining confidence function, a positioning-based dynamic location algorithm is obtained for cellular wireless location. At last, results of this data-fusion algorithm show that it improves location precision with the presupposition of robust decision.
