Abstract

The non-line-of-sight (NLOS) propagation is a key problem of subscriber location in cellular networks. The angle of arrival (AOA) and time/angle of arrival (TOA/AOA) position location (PL) estimation methods are presented to mitigate the NLOS propagation in this paper. In order to reduce the feasible region of the mobile station (MS) and to improve the accuracy of the location estimation, the angle spread measured AOA is constrained by the geometrically based single bounce circular model (GBSBCM) and the measured TOA is constrained by the fact that the measured TOA is always greater than the true TOA value. Its effectiveness is verified by the computer simulation.
