The thesis addresses the problems of analysis and modelling of ultrasonic Doppler signals in vascular applications and in the assessment of fetal pseudo-respiration. A method of modelling Doppler signals of flow velocity using time-varying filtering of white noise and generation of sinusoids is presented and applied to provide signals used further in this work. The inadequacy of the AR model to the...
W pracy przedstawiono nowe adaptacyjne metody i algorytmy odpomej (ang. robust) parametrycznejj identyfikacji sygnalów modelowanych liniowymi szeregami czasowymi. Wykazano, że dla szerokiej klasy sygnałów klasyczne odporne algorytmy parametrycznej estymacji, wywodzące się z kryterium asymptotycznej optymalności w sensie minimaksowym Hubera [17], nie są silnie zgodne, tj. nie zapewniają zbieżności...
