Title:
ADAPTIVE FREQUENCY CALIBRATION
Document Type and Number:
WIPO Patent Application WO/2018/098622
Kind Code:
A1
Abstract:
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.
