High resolution spectral analysis using a combination of an orthogonal approach and a genetic algorithm

We describe in this paper how a method for parsimonious sinusoidal representation of signals based upon an orthogonalization technique can be suitably modified by embedding it into a genetic algorithm. We first describe the orthogonalization formalism, then we present the genetic algorithms in general and the specific form, based on a floating-point parameter representation, that we have employed in this work. Experiments are presented and possible extensions are discussed.
