An extension of blind source extraction (BSE) of one or a group of sources to the case of ill-conditioned and post-nonlinear (PNL) mixing is introduced. This is achieved by a ldquomixed objectiverdquo type of cost function which jointly maximizes the kurtosis of a recovered source and estimates a measure of nonlinearity within the mixing system. This helps to circumvent problems with existing BSE methods, which are limited to noiseless and linear mixing models. Simulations illustrate the… CONTINUE READING
