Abstract

This study proposed Particle Swarm Optimization-based (PSO-based) estimation method to overcome the error of time difference of arrival (TDOA) in a reverberant environment. It uses numerical TDOA estimations to be the initial value and the information of TDOA of first reflective paths is considered. Moreover, the objective function utilizes the property of alignment to search for the TDOA of direct paths. And then the results of PSO, we will obtain three estimations of TDOA. It can simply enhance the signal quality.
