    Keywords : Affine Projection Algorithm APA ; Stereo Echo Cancellation SEC ; De-correlation; Non-linear Processing NLP ; Time Varying All-Pass Filter TV-APF ; ERLE; MIS.;

    Abstract : Monophonic tele-conferencing systems employ acoustic echo cancellation (AEC) to reduce echoes that result from coupling between loudspeaker and microphone. Acoustic echo cancellation is simple to develope as there is a single channel. READ MORE

  3. 2. 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
