A key component for hands-free, full-duplex, communication technology is the echo canceler. An echo canceler consists primarily of an adaptive filter and a control device called the double-talk detector. We derive a test statistic based on a normalized cross-correlation vector for the multichannel frequency-domain adaptive algorithm. The advantages of this approach are: low computational complexity, simplicity of implementation, and better performance than the classical Geigel algorithm. |
