Re: FSK4 Demodulation on the FPGA

looking for an implementation that’s entirely USRP based.
I am only looking to be able to get the demodulated symbols
on the USRP rather than doing it on the PC. Would I need to
implement all of the blocks you mentioned -

Correct. ISTR Stevie’s receiver has a squelch block as well…

Also, some of these blocks contain a lot of implied functionality that’s
currently furnished by GR - everything from plumbing to FIR filtering…

Best
