A Gauss-Newton method for blind source separation of convolutive mixtures
Sergio Cruces, Luis Castedo · 2002
In this paper we present several Gauss-Newton algorithms for blind source separation of convolutive mixtures. The algorithms can be interpreted as generalizations of two previous approaches due to Van Gerven and Van Compernolle (1995) and Nguyen-Thi and Jutten (1995). Since they are of the Gauss-Newton type, they exhibit a fast rate of convergence. Also, we present a stability analysis for two sources and instantaneous mixtures where we show that the algorithms cannot converge to non-separating solutions.
