A frequency-domain double-talk detector based on a normalized cross-correlation vector

A key component for hands-free, full-duplex, communication technology is the echo canceler. An echo canceler consists primarily ofan adaptive 4lter 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 ofthis approach are: low computational complexity, simplicity ofimplementation, and better perf ormance than the classical Geigel algorithm. ? 2001 Elsevier Science B.V.
