Abstract
We propose a new mobile station tracking algorithm based on the bootstrap filtering that uses the time difference of arrival (TDOA) measurements and the signal powers of the mobile station measured at several base stations. The proposed algorithm imposes nonlinear kinematic constraints on the state estimates without destabilizing the algorithm. Such constraints can be most naturally incorporated in the Bayesian bootstrap filtering framework (treating the constraints as perfect measurements without measurement noise). To verify the algorithm, simulation is performed and the result demonstrates that our algorithm gives better position estimate than the bootstrap filter without constraints or the constrained bootstrap filter using only one of TDOA measurement or signal power measurement.
