Abstract :
The present paper presents a source separation algorithm used for noise suppression. The complexity of the algorithm at hand is treated. A reformulation of the algorithm reduces the number of arithmetic operation by a factor of five. Measurement noise is discussed and remedies are suggested and presented in simulations. An alternative estimation of correlations is suggested which might be more suited for use in a custom circuit.
