Estimation of Delays and Attenuations for Underdetermined BSS in Frequency Domain
Underdetermined blind delayed source problem is studied in this paper. Firstly, on the basis of the searching-and-averaging-based method in frequency domain, the algorithm was extended to blind delay source model. Secondly, a new cost function for estimating the delay of observed signal was present; the delay was inferred in the single-signal intervals. Finally, the delayed sound experiments demonstrate its performance.
