Abstract
Recently, it has been observed that the complexity of
finite-impulse-response (FIR) filters using the
frequency-response masking technique can be
significantly reduced by simultaneously optimizing all
the subfilters. In order to reduce the filter complexity
even further, this paper considers the optimization a
class of FIR filters based on the use of the generalized
frequency-response masking approach originally
introduced by Lim and Lian. For this class of filters,
the two masking filters are constructed by using a
common filter part. Again, the simultaneous
optimization of all the subfilters is used, resulting in
a considerable reduction in the overall filter
complexity. An example taken from the literature
illustrates the benefits of the proposed approach.
