Bias removal technique for blind source separationwith noisy measurements
S.C. Douglas, Andrzej S Cichocki, Шун-ичи Амари · Electronics Letters · 1998
In blind source separation, measurement noise introduces biases in the estimated coefficients of the separation matrix. A simple modification to an adaptive algorithm for blind source separation is derived that mitigates these biases for reasonable signal-to-noise ratios when the correlations of the noises are known.
