Abstract:
A signal receiver and a method for separating a RDS signal component from a received signal is described. After the received signal has been downconverted to the baseband, the baseband signal is split up into a first baseband signal for a first signal path and a second baseband signal for a second signal path. The first baseband signal is highpass filtered and forwarded to a frequency synchronization unit that generates a frequency synchronization carrier. The second baseband signal is modified in accordance with the frequency synchronization carrier provided by the first signal path, and a synchronized baseband signal is obtained that still comprises the full range of the RDS signal's spectral components.
