Abstract
In this paper, we focus on solving the time delay as a separate
problem to the reconstruction of the microphone and sound locations.
The time delay estimation appears as one of the main steps in sensor
calibration problem, once the time delays are known or estimated, we
can solve the time-difference-of-arrival problems by converting them to
time-of-arrival problems. In this paper we make use of an alternating
projection approach for estimating time delays. We show both for
simulated and real data that alternative projecting algorithm yields
good estimates of the time delays, even when provided with bad initial
estimations. The method is also easy to implement and comparatively
fast.
