I have used the quadrature demodulator block on GMSK (which is also
non-continuous phase) with great success.
Also, the next problem is bit recovery, I don't really understand the
correlator block, could anyone
point me towards some documentation that would be grand. Am I supposed
to be using this or the
clock recovery block?
The clock recovery block will resample the data stream at the data
clock's frequency, yielding a stream of "soft bits". These can then
be fed to a bit-slicer to produce a stream of binary '1's and '0's.
