Abstract:
A filter bank divides the input signal into L bands having different passbands called unequal-passbands-filter bank. This type of filter bank can be obtained in various ways, for example, from an equal-passbands-bank in which the signals of each band are combined to produce new unequal-passbands. Recent results showed that unequal-passbands scheme has superior performance over equal-passbands scheme. In this paper, a new method shows a decrease in the number of taps in the separation stage of the blind source separation system is presented. Decreasing number of taps is necessary to decrease the complexity cost. Simulation results prove that the proposed technique indicate improvement the convergence using filter bank in octaves with decomposition which was observed for colored input that has low-pass characteristics.
