A digital receiver being adapted for receiving an MSK modulated signal, comprises a digital front-end unit (10) adapted for providing samples having a phase value (θmeasure) of a down-mixed signal, a phase compensation unit (11) adapted for compensating the phase value (θmeasure) by delivering a phase offset compensated sample having a phase value (θsync), and a coherent demodulator (12) adapted for recovering information content from the phase offset compensated sample. The phase compensation unit (11) is adapted for analyzing a phase value (θsync) of the phase offset compensated sample, calculating a phase offset value (θoffset) based on the phase value (θsync) of the phase offset compensated sample, and applying the phase offset value (θoffset) when delivering a subsequent phase offset compensated sample.
A digital receiver adapted for receiving an MSK modulated signal, the digital receiver comprising:
A method of carrier resynchronization of an MSK modulated signal in a digital receiver, the method comprising steps of:
