Hi Mark,
the gr-dvbt has a QPSK, QAM-16
and QAM-64 implementation of constellation for both Tx/Rx. The standard
it implements is ETSI 300 744 which is OFDM based in which each
subcarier is modulated using the modulations above.

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.

Hi Mark,
The problem is that GNU Radio does not have equalizers that can perform
sufficiently well for constellations such as 64-QAM. As far as I know, the
only one present is a simple decision feedback equalizer.
I'm working on implementing a few equalizers: a) 2D Triangulation, and b)
Whittaker
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
ther
