In urban environment with serious blocking ofdirect paths, the non-line-of-sight (NLOS)propagation influencesthe location estimation accuracy. In this article, a novelalgorithm.is developed, which can mitigate the NLOS errors inlocation estimation significantly. Utilizing multiantenna array,the information of scatterers that cause the NLOS propagation isobtained. Then, we combine the information with TOA/TDOAbased location algorithm to estimate the location of mobilestation (MS). The simulation results show that our method canmitigate NLOS errors and enhance the location accuracygreatly.
