19 Jun 2009	MATLAB Central Team	The C-FICA algorithm (Convolutive extension of FastICA) is a time-domain fast fixed-point algorithm that realizes blind source separation of convolutive mixtures. It is based on a convolutive sphering process (or spatio-temporal sphering) that lets the use of the classical FastICA updates to extract iteratively the innovation processes of the sources in a deflation procedure. For the estimation of the source contributions, we use a least-square criterion whose optimization is realized by a Wiener filtering process.
