Up: Guitton: Hybrid subtraction
Previous: Limitations of the method
I presented a method that improves the signal/noise separation.
This method incorporates a prediction-error filter in the standard
formulation of the noise removal by adaptive subtraction. By
whitening the signal spectrum in the data, this formulation leads
to an unbiased estimation of the matched-filter. As a result the
noise and signal can be separated when both are correlated.
