Evaluation of fast convergence algorithm for blind source separation of real convolutive mixture

Blind source separation for convolutive mixtures based on the joint diagonalization of power spectral density matrices

“…Contributions from the same source are likely to come from the same spatial direction, so that the position information of sources can be exploited [10,19,20].…”

“…Secondly, BSS approaches developed for instantaneous mixture separation are exploited for each of the frequency bins, and finally, separated signals of all the frequency bins are combined together to form the separated outputs. It has been shown that satisfactory separation can be achieved within all the frequency bins, but combining them together to recover the original sources is a challenging issue due to the unknown permutations associated with BSS of individual frequency bins [2,[7][8][9][10][11][12][13].…”
