But my problem still exist. I will simulate BER for a MCM system for a M-ary or 64-QAM. Now I have code for 64-QAM, but if I will use it for MCM what I should do? Definition of MCM is still same, sending e.g 100 of 64QAM simultaneously. Thank you for your answer and your time and consideration. I will waiting for your answer. regards, Hassan Hi Krishna,

M-ary means you can send e.g. 100 modulated signal, which every modulated signal can be 64-QAM or M-QAM. Don't mix M in M-ary with M in MQAM. May be I should say MCM or multy carrier modulation. So my question is how can we implement MCM (M-ary) for 64QAM to estimate BER for that? Regards, Hassan Hi Krishna,
