Abstract(in English) | In the blind source separation (BSS), a separation block is trained so as to make its output signals to be statistically independent. Since the frequency domain BSS has some degree of freedom, the wave form and frequency response of the separated signals may be changed from the originals, resulting in signal distortion. In this paper, a learning algorithm, suppressing the signal distortion, for the feedforward BSS, implemented in the frequency domain, is proposed. A condition on both complete separation and signal distortion free has been proposed. This condition is included in the learning process as constraint. Usefulness of the proposed learning algorithm is analyzed by using several kinds of the signal sources. |
