A system and method for use in a real time system and for processing a signal with a low signal-to-noise ratio (SNR). The system comprises a model for modeling an expected signal and a filter that uses the model for filtering the signal. The filter is used for generating a prediction of the signal and an error variance matrix. The system further comprises an adaptive element for modifying the error variance matrix such that the bandwidth of the filter is widened, wherein the filter behaves like an adaptive filter.
L'invention concerne un système et un procédé à utiliser dans un système en temps réel et permettant de traiter un signal présentant un faible rapport signal-bruit (SNR). Le système comprend un modèle destiné à modéliser un signal prévu et un filtre qui utilise ledit modèle pour filtrer le signal. Le filtre sert à produire une prédiction du signal et une matrice de variance d'erreur. Le système comprend en outre un élément adaptatif qui permet de modifier ladite matrice de façon à élargir la largeur de bande du filtre, ce dernier se comportant comme un filtre adaptatif.
