Abstract:
A carrier frequency offset (CFO) calibration method for calibrating a CFO of a receiver is proposed. The CFO calibration method includes: receiving at least one CFO estimation value generated by digital CFO estimation; generating a CFO adjustment value according to the at least one CFO estimation value; and adjusting an oscillation frequency of an oscillator of the receiver according to the CFO adjustment value.
