| Abstract(in English) | Feed-Forward (FF-) and FeedBack (FB-) structures have been proposed for Blind Source Separation (BSS). The FF-BSS systems have some degree of freedom in the solution space, and signal distortion is likely to occur in convolutive mixtures. On the other hand, FB-BSS structure is hard to cause signal distortion. However, the FB-BSS system requires a condition for the transmission delay time in the mixing process. The FF-BSS systems and the FB-BSS system are compared based on the transmission time delay in the mixing process. Even though the FB-BSS can provide good separation performance, there exit some limitations on location of the signal sources and the sensors. |
