First attempt at preamble detection was done after converting samples to a bitstream. This makes preamble detection conceptually simple, but means operating after loss of a lot of information, so the quality of detection is poor. Performing preamble detection on the samples looks more promising, as well as providing the phase information needed to direct the samples to bitstream conversion.
