Title (EN) SIMPLIFIED DE-ROTATION IN DIGITAL FM DEMODULATOR ARCHITECTURES
(FR) DEROTATION SIMPLIFIEE DANS DES ARCHITECTURES DE DEMODULATEUR FM NUMERIQUE
Abstract: front page image
(EN)The present invention relates to a digital receiver for FM signals, in particular to a new demodulator structure and demodulating method, by which according to a first aspect of the invention the usual complex de-rotation process is reduced to a simple addition/subtraction. According to a second aspect of the invention, the requirements for the sampling frequency necessary for processing the demodulator signals are reduced substantially.
(FR)La présente invention concerne un récepteurs numérique de signaux FM, en particulier une nouvelle structure de démodulateur et un nouveau procédé de démodulation, par lequel selon un premier aspect de l'invention, le processus de dérotation complexe est réduit à une simple addition/soustraction. Dans un deuxième aspect de cette invention, les exigences pour la fréquence d'échantillonnage nécessaire au traitement des signaux de démodulateur sont sensiblement réduites.
