Echo cancellation
no vote
Reference to a New Class of Doubletalk Detectors Based on Cross-Correlation (Jacob Benesty) implemented in MATLAB. Using the correlation method with robustness. Can detect single-end voice and double-end speech. Adaptive filter using NLMS can achieve fast convergence speed. Obtained a very good acoustic echo cancellation effect. Cons: algorithm is too large. Needs to further optimize the algorithm. Which can be transplanted into the DSP.

Echo cancellation AEC
no vote
A low computational complexity of double talk detection algorithm. Benesty method improvement. Reduce the disadvantage analysis of computational complexity: Adaptive echo cancellation in double talk detection technology is commonly used in cross-correlation detection technology. One problem with this method, that is, at some point, such as in the near-end signal the end times, signal energy plummeted to zero, because the algorithm used in the forgotten factor, slow signal energy is estimated to be reduced, thus causing delays in test results.
