Abstract: The present invention discloses an adaptive filtering method and system based on an error sub-band. The present invention includes performing analysis filtering processing on an error signal and an input signal to obtain an error sub-band signal and an input sub-band signal respectively; and performing calculation according to the input sub-band signal and the error sub-band signal to obtain a new adaptive filtering weight, and updating a weight in an adaptive filter.
