ABSTRACT:
Provided is an adaptive filter that can reduce the computational complexity. The adaptive filter includes: a segmentation unit for segmenting N number of input signals into G number of signal groups; sub-filter unit having G number of sub-filters, which are corresponding to each of the signal groups, for filtering the corresponding signal group; an addition unit for summating the output signals of the sub-filter unit; an error computing unit for generating an error signal by comparing the output signals of the addition unit with a desired signal; filter coefficient updating unit having G number of filter coefficient updating units, each of which is corresponding to each of the sub-filters, for updating the filter coefficient of the corresponding sub-filter; and a switching unit for inputting the error signal to any one of the filter coefficient updaters optionally with respect to an iteration number k.
