英文摘要	Though subband adaptive filter has been studied for several years and already widely used in real-time acoustic echo cancellation (AEC) systems, the study of doubletalk detector in subband AEC has not been reported. In this paper, two subband doubletalk detectors are proposed and simulated. An objective measurement is also employed to quantify the performance of the subband doubletalk detectors in contrast with fullband implementation. The simulation shows the proposed subband doubletalk detectors can increase the detection probability of doubletalk at least 3 percent over traditional fullband implementation under same false alarm probability.; EI; 0
