Claim One:
1. A method for adaptively updating coefficients in a filter for processing data, comprising the steps of: a) receiving a data sequence in the filter and processing the data sequence in accordance with the coefficients in the filter to produce a processed data sequence; b) separately filtering the data sequence with a first set of filter characteristics to generate a filtered data term for the coefficients; c) filtering the processed data sequence using a second set of filter characteristics, said second set of filter characteristics being structurally and/or functionally identical to said first set of filter characteristics; d) generating a filtered ideal processed data sequence from the processed data sequence using a third set of filter characteristics, said third set of filter characteristics comprising a subset of filter characteristics structurally and/or functionally identical to said first filter characteristics; e) generating a filtered error term for the coefficients from the filtered processed data sequence and the filtered ideal processed data sequence; and f) updating the coefficients in the filter of step a with each of said filtered data term and said filtered error term.
