complex GMSK demodualtor with knowledge about preamble

Started by Pavel Schukin September 8, 2007
Hello, everybody!
I have a question about baseband GMSK signal demodulation.
For my signal parameters are following: 
1) BT=0.3, 
2) Symbol rate equals sample rate
3) I know preamble sequence
I suppose to apply match filter on preamble sequence for timing and
frequency offset recovery. Is this method appreciable for baseband GMSK?
Can i do something for demodulation having only baseband signal or i need
to frequency demodulate it?
