Abstract

Based on a parametric planar rotation updated algorithm and the deflation technique, a blind signal extraction method is proposed in underdetermined mixtures. While extracting one, source signal from the mixtures and keeping size of the mixtures, a separated signal is concealed from the mixtures using the deflation technique. This procedure is repeated for the deflated mixtures until all source signals are separated. The method is easy to be implemented with fast convergent speed and unknown source numbers. Computer simulation confirms its validity.
