Wireless frequency calibration device and method

The invention discloses a wireless frequency calibration device and method. The wireless frequency calibration device comprises a wireless receiver for receiving, amplifying and sampling a wireless calibration signal; a frequency detection module for recognizing whether the wireless calibration signal is a reference frequency; a frequency measurement module for measuring the reference frequency based on an oscillation frequency of a local oscillator so as to obtain a measurement result when the frequency detection module recognizes that the wireless calibration signal is the reference frequency; and a judging calibration module for judging whether the oscillation frequency is higher or lower than the reference frequency according to the measurement result, and calibrating the oscillation frequency of the local oscillator according to the judgment result. The device and the method disclosed by the invention have the advantages of being low in cost and easy to implement.
