- W1516389421 abstract "In this paper, we introduce a new blind source separation (BSS) method for linear instantaneous mixtures, which only assumes the sources to be uncorrelated. It is based on the time-segmented frequency- dependent real coherence function of the observed signals. This parameter makes it possible to detect time-frequency zones where only one source is active. Such zones are then used to identify the required separating coefficients by means of ratios of power spectral densities of the observed signals. This BSS method yields very high performance for mixtures of speech and/or noise signals, i.e. SNR improvements range from 50 dB to more than 90 dB." @default.
