  • Carrier frequency offset calibration method and system
    Patent number: 9397764
    Abstract: A carrier frequency offset calibration method and a carrier frequency offset calibration system are provided. The carrier frequency offset calibration method is adapted to calibrate the carrier frequency offsets of a transmission signal which includes a primary carrier and a secondary carrier. In the carrier frequency offset calibration method, the transmission signal is analyzed according to known carrier frequencies, a primary feedback value and a secondary feedback value, so as to obtain a primary carrier offset value and a secondary carrier offset value. The relationship between the primary carrier offset value and the secondary offset value is considered to determine whether to adjust the primary feedback signal and the secondary feedback signal.
