<p>A method for demodulating a radio frequency signal having a frequency (f), by oscillating a demodulator (70) at a frequency (F) different from the signal frequency (f), and measuring a DC offset value at this different frequency (F), the DC offset value being associated with interference. Then the demodulator (70) is oscillated at the signal frequency (f), thereby providing a demodulated signal. The DC offset value is subtracted from the demodulated signal in order to provide demodulated signal with a substantially reduced DC component. The demodulated signal is then monitored for further DC offset components, and these further DC offset components are subtracted from the demodulated signal. <IMAGE></p> |
