A simple and efficient method of multipath rejection (MPR) in Multipath fading channels for location estimations

Abstract

This paper proposes and evaluates a simple and efficient method to mitigate the positioning error caused by Multipath fading channels. Using geometric properties of the correlated received signals and Monte Carlo simulations, a lookup table has been developed to correct the TDOA estimation error. The performance of this multipath rejection (MPR) method has been evaluated for 3GPP wireless network standards. Simulation results show that the proposed method reduces the TDOA estimation error significantly and therefore improves the accuracy of mobile position estimation.
