mPSK modulation/demodulation

Hi Gnu Radio- community,

I am a student of communication engineering and I
am new in Gnu Radio. I am implementing a genetic algorithm for cognitive
radio on Gnu Radio and its hardware @2.4Ghz.
One parameter is modulation order. I would like to use 2,4,8, and 16
it is possible I prefer non-differential modulation. Until now I have
looking around the libraries and trying to get the stuff running. But
success. I tried
k/gnuradio-examples/python/gmsk2?rev=1644 Can someone tell me, if these
( and corresponding) should work? If not, do u know of a
possibility to use ready-built mPSK modulation/demodulation?

thanks for your help and attention.

Best regards - chris
