A method and apparatus for joint noise and echo cancellation of a two microphone system subject to cross-talk. The method includes estimating the reference output by removing the cross-talk and the estimated echo from the reference channel, when an echo is detected in the reference echo signal, adapting filters H13 and H23 by NLMS, when the estimated primary output includes speech, adapting filters H12 and H21 by de-correlation, when neither echo nor speech is detected, adapting filter H12 is adapted by NLMS, obtaining the primary output and the reference output by post-filtering of the estimated primary output and the estimated reference output, respectively, and utilizing the primary output and the reference output for canceling the echo and noise of a two microphone system subject to cross-talk. |
