ABSTRACT:
In an FSK modulated signal receiving station a synchronization sub-system is arranged to sample the received signal and to select one sample per symbol within a detection window having a finite length, said samples being selected at predeterined instants. This produces a number of versions of the sampled signal and these different versions of the signal are then processed in parallel to determine the signal timing and the signal frequency offset.
