Abstract
In this paper, we present two new computationally efficient frequency-response masking (FRM) filter structures that combine the well-known FRM technique and prefilter-equalizer approach. Several multiplication-free prefilters are introduced for the proposed FRM filter structures. We show, by means of an example, that the newly developed prefilter-equalizer based FRM structures yield as much as 32% reduction in terms of the number of arithmetic operations compared to the original FRM approach.
