For the demodulation of modulated carrier signals (AS) supplied to the cordless telecommunication apparatus, a data comparator (1212) is used in the cordless information transmission, especially a DECT-specific information transmission, which data comparator is supplied for this purpose with a reference signal (RS) generated by integration of the carrier signal (AS) at an input (E2) for the purpose of demodulating the carrier signal (AS). Since, according to the DECT transmission convention, two identical bit values of a synchronization word (S-Bw) must also be detected in addition to the demodulation, a decision threshold (ES) of the reference signal (RS) is changed by as error value (dES). In the cordless telecommunication apparatus, a compensation arrangement (16, 19, 142) which compensates for this error value (dES) is therefore additionally provided.

Pour démoduler des signaux porteurs (AS) modulés, acheminés à un appareil de télécommunication sans fil, on utilise un comparateur de données (1212) pour la transmission sans fil d'information, notamment pour la transmission d'informations spécifique de la norme DECT, à une entrée (E2) duquel est conduit un signal de référence (RS) produit par intégration du signal porteur (AS), afin de démoduler le signal porteur (AS). Comme selon l'accord de transmission DECT, outre la démodulation, il faut également reconnaître deux valeurs binaires identiques d'un mot de synchronisation (S-BW), un seuil de décision (ES) du signal de référence (RS) est modifié par une valeur d'erreur (dES). Un système de compensation (16, 19, 142) supplémentaire est de ce fait prévu dans l'appareil de télécommunication sans fil, pour compenser cette valeur d'erreur (dES).
