Second-Order Criterion for Blind Source Extraction

Abstract : A second-order criterion for blind signal extraction in instantaneous linear mixtures has recently been proposed. It is proved that, with an adequate choice of autocorrelation time lags, the criterion leads indeed to a successful source extraction in the noiseless case. Using this criterion, the source identifiability conditions turn out to be the same as in the popular second-order blind identification method for blind source separation.
