3. Redução de ruído em sinais de voz usando curvas especializadas de modificação dos coeficientes da transformada em co-seno. / Speech denoising by softsoft thresholding.
Many noise-reduction methods are based on the possibility of representing the clean signal as a reduced number of coefficients of a block transform, so that cancelling coefficients below a certain thresholding level will produce an enhanced reconstructed signal. It is necessary to assume that the clean signal has a sparse representation, while the noise ener
