Title (EN) ADAPTIVE FREQUENCY CALIBRATION
(FR) ÉTALONNAGE DE FRÉQUENCE ADAPTATIF
Abstract:
(EN) According to implementations of the subject matter described herein, a new approach for adaptively calibrating frequency is proposed herein. Generally speaking, a device determines, upon receipt of a signal from another device, a quality of the received signal. Then, the device obtains a frequency offset based on the quality of the signal, and calibrates a local frequency generator of the device based on the frequency offset. In this way, an error between the local frequency generator and a frequency generator of the further device can be reduced. As a result, high-qualified radio synchronization and connection can be guaranteed, even when the device is under poor radio coverage.
(FR) La présente invention concerne, selon certains modes de réalisation, une nouvelle approche pour étalonner de manière adaptative une fréquence. De manière générale, un dispositif détermine, lors de la réception d'un signal provenant d'un autre dispositif, une qualité du signal reçu. Ensuite, le dispositif obtient un décalage de fréquence sur la base de la qualité du signal, et étalonne un générateur de fréquence local du dispositif sur la base du décalage de fréquence. De cette manière, une erreur entre le générateur de fréquence local et un générateur de fréquence de l'autre dispositif peut être réduite. Par conséquent, une synchronisation et une connexion radio de haute qualification peuvent être garanties, même lorsque le dispositif est sous une mauvaise couverture radio.
