  • Study on a Method of Blind Source Separation Using Variable-Density Complex Discrete Wavelet Transform

抄録

<p>This paper presents new blind source separation method using Variable-Density Complex Discrete Wavelet Transform (VD-CDWT). In the conventional method by MNMF using STFT, selection of STFT frame size has an influence on the performance of sound source separation. Therefore, it is required to set an appropriate flame size. In this research, the influence of selection of STFT frame size on the performance of MNMF is investigated. And new blind source separation method is proposed to solve this problem.</p>
