    摘要: This invention relates to a receiver comprising: a phase detector with a first and second input, the first input being adapted to receive a modulated input signal; a comparator comprising an input coupled to an output of the phase detector; a frequency-offset cancellation block comprising an input coupled to an output of the comparator. The receiver includes a digitally controlled oscillator comprising: a control input coupled to an output of the comparator and an output of the frequency-offset cancellation block; and an output coupled to the second input of the phase detector.
