A receiver of a frequency modulation (FM) signal includes an antenna, a tuner, an analog-to-digital converter (ADC), a demodulation module and a frequency offset estimation module. The antenna receives a FM signal. The tuner coupled to the antenna is for converting the FM signal into an intermediate frequency signal. The ADC coupled to the tuner is for converting the intermediate frequency signal into a digital intermediate frequency signal. The demodulation module coupled to the ADC is for demodulating the digital intermediate frequency signal into an audio signal based on a frequency offset compensation signal. The frequency offset estimation module coupled to the demodulation module is for generating the frequency offset compensation signal according to the audio signal.
