The invention relates to a method for resampling at transmission and reception of a digital signal with digital band translation. According to the invention, a resampling (25) is performed upon reception of a bandpass signal, whereby the signal is translated (4) to baseband with a configurable frequency and the resulting baseband signal is introduced into a decimator (5). In addition, a resampling (26) is performed upon transmission, whereby the baseband signal is interpolated (10) and, subsequently, translated to bandpass (20) with a configurable frequency. The inventive method can be used to correct the frequency error introduced by digital/analogue (11) and analogue/digital (1) converters. Moreover, the set formed by the band translation and the aforementioned resampling can be used to simplify the complexity of the interpolation filters used to generate new samples of the digital signal.

L'inention concerne un procédé de rééchantillonnage (25) dans la réception d'un signal passe-bande au cours duquel le signal est transféré (4) dans la bande de base avec une fréquence configurable et le signal de bande de base obtenu est introduit dans un décimateur (5). Le procédé de l'invention consiste également à effectuer un rééchantillonnage dans la transmission (26) au cours duquel le signal de bande de base est interpolé (10) pour être ensuite transféré dans la bande passante (20) avec une fréquence configurable. Ce procédé permet de corriger une erreur de fréquence générée par les convertisseurs numérique-analogique (11) et analogique-numérique (1). De plus, l'ensemble formé par la translation sur bande et le rééchantillonnage proposé permet de simplifier la complexité des filtres d'interpolation utilisés pour générer de nouveaux échantillons du signal numérique.
