I'm not sure how integrate the correlation sync block with gmsk. It expects modulated symbols and I'm not sure how to generate a modulated vector of gmsk symbols. There doesn't seem to be a gmsk class that can be used by the modulate vector block.
Thanks,
Alex

Yeah, the MSK TED selections for the symbol sync block expect the constant envelope FSK waveform on the input. Demodulation from FSK to baseband pulses should happen after the symbol sync block.
