A simple closed-form solution for overdetermined blind separation of locally sparse quasi-stationary sources
2012
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
We consider the scenario of an unknown overdetermined instantaneous mixture of quasi-stationary sources. Blind source separation (BSS) under this scenario has drawn much attention, motivated by applications such as speech and audio separation. The ideas in the existing BSS works often focus on exploiting the time-varying statistics characteristics of quasi-stationary sources, through various kinds of formulations and optimization methods. In this paper, we are interested in further assuming
