Title (EN) SIGNAL PHASE CONTROL IN AN INTEGRATED RADIO CIRCUIT
(FR) RÉGLAGE DE PHASE DE SIGNAL DANS UN CIRCUIT RADIO INTÉGRÉ
Abstract: front page image
(EN) An apparatus and method to control signal phase in a radio device includes a phase rotator configured to control a phase of a local oscillator. A phase error determination module is configured to determine phase error information based on received in-phase (I) and quadrature (Q) (IQ) signal values. A phase correction module is configured to derive from the received IQ signal values a correction signal and apply the correction signal to the phase rotator in a path of the local oscillator.
(FR) La présente invention concerne un appareil et un procédé de réglage de phase de signal dans un dispositif radio comportant un mécanisme de rotation de phase configuré pour le réglage d'une phase d'un oscillateur local. Un module de détermination d'erreur de phase est configuré pour la détermination d'une information d'erreur de phase en fonction de valeurs (IQ) de signal reçu en phase (I) et en quadrature (Q). Un module de correction de phase est configuré pour la dérivation à partir des valeurs IQ de signal reçu d'un signal de correction et pour l'application du signal de correction au mécanisme de rotation de phase dans un trajet de l'oscillateur local.
