I've been working towards an FSK demodulator scheme using GNU radio (more
specifically, the signals are GFSK)
I've read through this example:
Specifically it talks about the "add_const" block, the value of which was
determined by trial and error for the specific data set in use.
This "constant" is actually the frequency error value
Here, in this slide deck (slide 2)
They show a frequency correction feed back loop from the FSK4 demodulator to
the front end, but uses a custom module.
I'm looking for a simpler way to do this using "stock components" that are
already in Gnu Radio.
I can of course - make this work for one specific transmitter, and one specific
receiver. This solution does not work well when I have 50 different
transmitters, I need a solution that can adjust dynamically.
Any suggestions for stock components? Or another example?
