Experimental comparison of signal subspace based noise reduction methods
Peter Hansen, Per Christian Hansen, S.D. Hansen, John Aasted Sørensen · 1999
The signal subspace approach for non-parametric speech enhancement is considered. Several algorithms have been proposed in the literature but only partly analyzed. Here, the different algorithms are compared, and the emphasis is put onto the limiting factors and practical behavior of the estimators. Experimental results show that the signal subspace approach may lead to a significant enhancement of the signal to noise ratio of the output signal.
