A bit synchronization method is proposed. The method includes buffering a plurality of samples from a signal stream, scanning the buffered samples for transitions and updating a zero-crossing histogram buffer upon detection of the transitions. The method further includes detecting at least two peaks simultaneously from the updated zero-crossing histogram buffer, fixing at least two boundaries from the detected peaks, and integrating the buffered samples within the boundaries. Finally the method includes generating an output signal comprising a synchronized bit stream from the integrated samples. |
