I used QAM_constellation.py code for constellation ploting of 16 QAM . Why it does not support for order 16? how should I make it work? any alternative for 16QAM demod?Hi all,I crated a block named costas_loop_cc. it works fine for 2psk, 4psk,4qam and 8psk. But it does not support to 16QAM i.e order 16. when I execute with order 16 it shows the error like this:
