发明名称 DELAYED ADAPTATION STRUCTURE FOR IMPROVED DOUBLE-TALK IMMUNITY IN ECHO CANCELLATION DEVICES
摘要 In a system having an adaptive filter block for receiving a reference signal and adapting to an input signal, and a block for detecting corruption of the input signal by an interference signal and in response limiting adaptation of the adaptive filter block, the improvement comprising delaying and applying the input signal to the adaptive filter block while applying the input signal to the block for detecting corruption without delay.
