Hi Tom, Yes i've already done the simulation with 16 QAM and even 64 QAM by following your example for MPSK. The simulation was very good even I add noise in the channel model. I had only problem of power, if the transmitting power is high enough the transmission is perfect with no errors. On air, I tried to add timing, frequency, and phase correction block but after running transmitting flow graph the simulation at receiver . what do you think about that?
