Abstract
In urban environment with serious blocking of direct paths, the non-line-of-sight (NLOS) propagation influences the location estimation accuracy. In this article, a novel algorithm is developed, which can mitigate the NLOS errors in location estimation significantly. Utilizing multiantenna array, the information of scatterers that cause the NLOS propagation is obtained. Then, we combine the information with TOA/TDOA based location algorithm to estimate the location of mobile station (MS). The simulation results show that our method can mitigate NLOS errors and enhance the location accuracy greatly.
