Abstract
In an example embodiment, a method for adjusting a phase of a carrier replica signal includes receiving, by a tracking loop, a digital baseband signal, generating within the tracking loop the carrier replica signal, generating within the tracking loop a sequence of samples from the digital baseband signal and the carrier replica signal, and controlling a phase of the carrier replica signal depending on the sequence of samples. The example method further includes receiving a trigger signal indicating an upcoming phase shift of the digital baseband signal, blanking the tracking loop and controlling the phase of the carrier replica signal using a constant value, determining a magnitude of the phase shift, adjusting the phase of the carrier replica signal using the determined magnitude of the phase shift, and un-blanking the tracking loop and controlling the phase of the carrier replica signal depending on the sequence of samples.
