摘要
According to an embodiment of the present invention, as the reference signal is output through the speaker, the residual echo estimator for estimating the residual echo size of the microphone signal input to the microphone is: the size of the linear echo of the reference signal in the current frame and the past frame It is configured to estimate the size of the residual echo in the current frame using the size of the linear echo of the reference signal at and to update the weights applied to the sizes of the linear echo.
