Combination schemes are gaining attention as an interesting way to
improve adaptive filter performance. In this paper, we present some
recently proposed practical schemes for convex and affine filter combination,
explaining how they can be useful to overcome some of the
most important limitations of conventional adaptive filters. We will
also illustrate the benefits of this approach with several experiments.
First, we explain how the combination can reduce the mean square error
(MSE) of adaptive filters by biasing their outputs. We present also
some recent results in real scenarios for acoustic echo cancellation.
