Subspace Decomposition Applied to Speech Enhancement
Mohamed Najim · 2008
The subspace method can potentially be used in the field of speech enhancement using a single microphone.In this context, our purpose is to estimate the signal k s using observations disturbed by a white additive noise k b .Instead of directly operating on the correlation matrix, an alternative procedure is to carry out the singular value decomposotion of the noisy observations' Hankel matrix.This algorithm consists of three steps: Modeling, Estimation and Optimal Filtering in Signal Processing
