Title: Enhanced blind signal source separation algorithm for highly correlated mixtures
Inventor: WANG SONG
IPC: H04R3/00
Filed: 2012-11-07
Abstract: PROBLEM TO BE SOLVED: To provide an enhanced blind source separation technique to improve separation of highly correlated signal mixtures.SOLUTION: A beamforming algorithm is used to precondition correlated first and second input signals S, S. The beamforming algorithm applies spatial filters 211 to the first signal and the second signal in order to amplify signals from a first direction while attenuating signals from other directions. Such directionality serves to amplify a desired speech signal in the first signal and attenuate the desired speech signal from the second signal. Blind source separation 210 is then performed on the beamformer output signals to separate the desired speech signal and the ambient noise and reconstruct an estimate of the desired speech signal. To enhance the operation of the beamformer and/or blind source separation, calibration is performed at one or more stages 208, 213, 215.
