Doubletalk Detector Performance Evaluation in Acoustic Echo Cancellation
碩士 === 國立交通大學 === 電信工程系所 === 96 === In the adaptive acoustic echo cancellation, double talk can make the adaptive filter diverge from the optimum. In this thesis, the cross-correlation between the microphone signal and estimate echo is used to judge whether double-talk arises. We also derive the the...
