Abstract

A method for the detection and estimation of periodicities in noisy signals. First the signal is sampled and preprocessed in a discrete succession of equal periods. Then, short term characteristics vectors are generated for each period. The short term characteristics vectors are then grouped into sets, followed by the obtainment of at least one representative vector for each set. Periodic structures are estimated using the representative vectors. In a preferred embodiment, the short term characteristics are the the short term spectra of the signal. Practically, an autocorrelation matrix is constructed to assess autocorrelation along a diagonal.
