Assignee: WIDEX A/S
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A digital receiver adapted for receiving an MSK modulated signal, the digital receiver comprising:
a digital front-end unit configured to provide samples having a phase value (θmeasure) of a down-mixed signal;
a phase compensation unit comprising circuitry configured to compensate the phase value (θmeasure) by delivering a phase offset compensated sample having a phase value (θsync); and
a coherent demodulator configured to recover information content from the phase offset compensated sample;
wherein the phase compensation unit is configured to:
analyze a phase value (θsync) of the phase offset compensated sample using analyzer circuitry,
calculate a phase offset value (θoffset) based on the phase value (θsync) of the phase offset compensated sample using calculation circuitry, and
apply the phase offset value (θoffset) when delivering a subsequent phase offset compensated sample.
