Hello Alitsu,
Now I changed user defined sequence in whole system. Now I am attaching the file again. I am trying to get 4-QAM but its constellation diagram shows only two points but I am getting the proper output what I have given as input. For 64 QAM, they QAM sequence generator bits/per symbol =6.( i.e h=6 and M=8) that’s why In 4 QAM I changed bits/per symbol = 2(i.e h=2 and M=2).
I have attached 64 QAM and 4QAM files.
Thanks in advance.
