Double-talk-robust prediction error identification algorithms for acoustic echo cancellation
T van Waterschoot, G Rombouts… - IEEE Transactions …, 2007 - ieeexplore.ieee.org
The performance of an acoustic echo canceller may be severely degraded by the presence
of a near-end signal. In such a double-talk situation, the variance of the echo path estimate …
