Abstract
Due to ambiguities and estimation errors, combining time differences of arrival (TDOAs) for simultaneous localization of multiple acoustic sources is a challenging task. This paper studies this problem under the framework of consistent graphs and proposes an efficient algorithm to determine TDOAs originating from the source.
