Only half of the solution, but there's a fully functional
64-QAM transmitter for bladeRF here:
https://github.com/argilo/gr-qam
It implements the North American CATV standard
ANSI/SCTE07 also known as ITU-T J.83 Annex B.
We're just using cable ready TV's as receivers.

I'm looking for an example of a higher-order modulation implemented
successfully in GNU Radio with an SDR frontend. I've seen bpsk, GMSK,
etc. implemented over a wireless channel, but I've only seen
simulations of higher-order modulations. Could someone point me
towards one or confirm that there's no examples?
