[0216]In order to illustrate the technical effect of the present invention, a specific example is adopted to carry out experimental verification of the present invention, and its experimental effect is compared with four kinds of contrast algorithms, and four kinds of contrast algorithms are respectively: classic generalized cross-correlation-phase transformation method (GCC -PHAT) (see literature "Y.Huang, J.Benesty, and J.Chen, Acoustic MIMO Signal Processing. Berlin, Germany: Springer, 2006."), normalized multi-channel frequency-domain LMS algorithm (NMCFLMS) (see literature “J.Chen, Y.Huang, and J.Benesty, “An adaptive blind SIMO identification approach to joint multichannel time delay estimation,” in Proc.IEEEInt.Conf.Acoust., Speech, Signal Process.(ICASSP), 2004, pp .IV-53–IV-56."), Robust Normalized Multichannel Frequency-Domain LMS Algorithm (RNMCFLMS) (see literature "M.A.Haque and M.K.Hasan, "Noiserobust multichannel frequency-domain LMS algorithms for blind channel ...
