WebIn this paper, we propose an adaptive method for blind separation of convolutively mixed sources. The method is an extension on the basis of two-stage separation approach using fourth-order cumulant. As in the case of instantaneous mixtures, the ... Decorrelation is a general term for any process that is used to reduce autocorrelation within a signal, or cross-correlation within a set of signals, while preserving other aspects of the signal. A frequently used method of decorrelation is the use of a matched linear filter to reduce the autocorrelation of a signal as far as possible. Since the minimum possible autocorrelation for a given signal energy is achieved by equalising the power spectrum of the signal to be similar to th… how does fartlek training improve fitness
