A fusion location algorithm optimization based on AHP

针对LTE网络,在非视距传播环境下提出了一种基于层次分析法的混合定位算法以提高定位的鲁棒性。利用AOA、TDOA、PDOA得到相应测量值,利用得到的测量值分别估算出移动台的位置;再针对三种算法各自特点利用层次分析法构造对比矩阵,计算出权重向量;最后根据层次分析法进行数据融合得到移动台最后的估计位置。仿真结果表明,该基于层次分析法数据融合的移动台定位算法准确,提高了定位鲁棒性。

This paper proposed a fusion location algorithm based on AHP for cellular networks under NLOS propagation environment to improve the robustness. First of all, use AOA, TDOA and PDOA measurements to eliminate position of the mobile station. For each of the three algorithms, compare the characteristics of structure matrix to calculate the weight vector. Use AHP data fusion to get the final estimate of the position of the mobile station. Simulation results show that the mobile station positioning algorithm based on AHP accurate data fusion in general can meet the accuracy requirements and improve the robustness.
