Abstract:
The invention relates to recovering a carrier for a synchronous demodulator, that receives an input signal. A carrier is reconstructed for the provided input signal, and the input signal (in) and carrier (tr) are mixed to generate a mixed signal to be outputted (i, q), wherein a residual phase error of the mixed signal is corrected by a phase shift to provide a phase corrected output signal.
