4. 3. Blind source separation in real time using Second Order statistics

   University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Author : Lakmal Silva; Zhu Bo; [2007]
   Keywords : Blind source separation; convolutive mixtures; second order statistics; Adaptive decorrelation; Real time processing;

   Abstract : A multi stage approach to speech enhancement methods improves the quality of separation over standard techniques such as spectral subtraction and beamforming. Two algorithms are implemented for convolutive mixtures in two of the important stages of a speech enhancement system, the source separation stage and the background denoising stage. READ MORE
