New method for estimation of DOA based on fast independent component analysis

Independent Component Analysis (ICA) is a novel blind source separation method. As a new technique of signal processing, ICA has become more and more important and has been widely used in communication, processing of radar signals, image processing of biological medicine, pattern recognition and so on. In this paper, the fundamental theory and algorithm of ICA were presented. And a new method—fastICA was used for DOA estimation. A simple estimation method of DOA can be obtained. Experimental results have verified its feasibility and effectiveness.
