[Discuss-gnuradio] CPFSK

[Andrew Buck]

Hi,

I'm trying to demodulate and decode a CPFSK signal generated by a
non-gnuradio source.  I'm new to gnuradio and RF in general.  I know
that GMSK is a form of CPFSK, so I started by trying that, but I haven't
had success.  I noticed that the gmsk code is in the limbo directory, so
I'm not sure if it's currently in a working state.  Also, as I said, I'm
new to RF, but I found it strange the the GMSK demodulation did not
appear to require a parameter specifying the frequency delta between the
mark and space frequencies.  Can anyone help me out by telling me if
GMSK is what I should be using, what the current state of the GMSK code
is, and why the GMSK code doesn't require the frequency delta (I'm sure
I'm not using the correct term here).

Thanks for your help.
