Abstract
The invention provides a carrier frequency offset processing method, an apparatus and a receiver. The method comprises: 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 to obtain a statistical value of carrier frequency offset between a receiving module and a transmitting module; and dynamically adjusting, according to the statistical value of carrier frequency offset, a bandwidth of a low-pass filter through the software and hardware interface. The invention realizes dynamic adjustment of the bandwidth of the low-pass filter in the process of a receiver receiving signals, solving the problem of the impact on processing performance brought by the fixed bandwidth of a low-pass filter in the prior art.
