Abstract(in English) | In this paper, we propose a signal separation system that attempts to separate two source signals without the information of these signals.This system is divided into two steps.In Step1, it separates and enhances both source signals by Blind Deconvolution using AMUSE(Algorithm for Multiple Unknown Signals Extraction)method with a DOA(Direction Of Arrival)of a source signal, which have higher power, is estimated by DSA(Delay-and-Sum Array)method.Step2 estimates a DOA of 2nd source by DSA method using enhanced signal corresponding to the 2nd source, and separates two source signals again by applying the adaptive notch filter on output signals of AMUSE method.Computer simulations show that two source signals can be separated by the proposed method.However there is necessity to improve the separating ability to 2nd source signal. |
