ADAPTIVE FILTERING METHOD AND SYSTEM BASED ON ERROR SUB-BAND |
摘要 |
The present invention discloses an adaptive filtering method and system based on an error sub-band, and relates to the field of signal processing technologies, so as to reduce the amount of calculation of an adaptive filtering algorithm. 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. Embodiments of the present invention are applied in an adaptive filtering process. |
