摘要

This paper first describes a trial of estimating the time delays or the distances between receivers and sound sources based on the complex ICA, especially for the mixed observations with time delays. This method enables us to find the sound source positions or the directions of arrival. Further, we can easily construct an inverse filter to separate the (overall) real mixed signals using the parameters estimated by ICA, while the usual complex ICA requires synthesizing all frequency components. Finally, through simulation, we demonstrate the high-quality blind separation as well as the validity for the estimation of the source parameters.
