Claim:
1. A carrier frequency offset processing method, comprising: receiving, through a software and hardware interface, an estimated value of frequency offset of a data packet transmitted by an automatic frequency offset control module; collecting the received estimated value of frequency offset of the data packet and performing statistical analysis on the collected estimated value of frequency offset of the data packet to obtain a statistical value of carrier frequency offset between a receiving module and a transmitting module; dynamically adjusting, according to the statistical value of the carrier frequency offset, a bandwidth of a low-pass filter through the software and hardware interface; and feeding the statistical value of carrier frequency offset back to a local oscillator, so as to allow the local oscillator to compensate and adjust a frequency of the local oscillator according to the statistical value of carrier frequency offset and the estimated value of carrier frequency offset.
