Abstract:
1. An adaptive filter, comprising: a segmentation means for segmenting N number of input signals into G number of signal groups wherein N and G are an integer not less than 1; sub-filter means having G number of sub-filters, which are corresponding to each of the signal groups, for filtering the corresponding signal group; an addition means for summating the output signals of the sub-filter means; an error computing means for generating an error signal by comparing the output signals of the addition means with a desired signal; filter coefficient updating means having G number of filter coefficient updating units, each of which is corresponding to each of the sub-filters in the sub-filter means, for updating the filter coefficient of the corresponding sub-filter; and a switching means for inputting the error signal to any one of the filter coefficient updating means optionally with respect to an iteration number k, wherein the iteration number k is an integer number not less than 1 and represents the number of performing entire operations of the adaptive filter.
