Could not find a Constellation Demod that goes with the Constellation Modulator

[George Edwards]

Hello,

Is there a constellation Demodulator that goes with the Constellation
Modulator in the Gnuradio blocks? Any suggestions on how to build one with
the available blocks?

Building it will be tricky because the available blocks would need to do
the signal processing that captures the correct sampling time at 1-sample
per symbol.

Thanks for your help.

Regards,
George
