Abstract
The field of Digital Signal Processing (DSP) is
concerned with the restoration of signals which have
undergone distortion and interference or noise
corruption as a result of being transmitted. The usual
way to recover such a signal is by adaptive filtering.
Designing adaptive filters is not an easy task. It
usually involves complicated algorithms whose
performance depends on the skill of the designer as
well as the power of the computer used. The aim of the
present work is to provide a way of automating such
process by means of a black box technique. In this
approach, both the structure and the parameters of
adaptive filters are evolved. The former is done by
Genetic Programming (GP) and the latter is done by
Simulated Annealing (SA). The power of the hybrid GP/SA
is demonstrated with some results on three interesting
DSP applications: channel equalisation, noise
cancellation and interference removal.
