摘要：

Implementations of adaptive filters using field programmable gate arrays require the ability to change the coefficient values of the filter based on the adaptation algorithm. Multiplierless filter designs rely on a prion knowledge of the coefficient values to implement the filter using hard-wired shifts and additions. We describe a multiplierless approach to adaptive filter implementation that reduces the complexity from quadratic to linear in the number of bits.
