Abstract
A method for determining a time difference between a first and a second time of arrival of the signal is described, the method including: receiving a first representation of the signal at the first time of arrival; receiving a second representation of the signal at the second time of arrival; correlating at least a first time-domain representation of the signal and a second time-domain representation of the signal to obtain a first time difference information; evaluating a phase difference relation between a first frequency-domain representation of the signal and a second frequency-domain representation of the signal to obtain a second time difference information; and determining the time difference between the first and the second time of arrival of the signal based on the first and the second time difference information, or based on a time difference information derived from the first time difference information and the second time difference information.
