ABSTRACT:
A source characterization system (8) which, starting from linear convolutive mixtures E(t) of primary signals X(t) from sources (S1-Sn), determines signals F(t) which form an estimate of a characteristic variable of at least one primary signal X(t). This variable may be an average energy, a spectral density or an autocorrelation function. A pre-processing device (20) enables the signals E(t) from the mixtures to be pre-processed before they are applied to the source separation device (10). The measured variable may serve to retroact on the operation of the sources. The source characterization system may be used for the control of apparatuses for transmitting and/or receiving electric, acoustic or electromagnetic signals.
