Hi alistu, now I am using Quadrature demodulator. and about constellation, I used four iterations with different BitsPerSymbol, 2, 4, 6, and 8 respectively. so 4QAM, 16 QAM, 64 QAM, and 256 QAM are used in the model.

Actually, I am still facing the same problem.
Please check the attached file.

Hi alistu. Actually, I used the blocks diagram for Quadrature demodulator on receiver side. It can be found in the attached picture below. but never-mind I will change it

Hello Sam. For OOK, I did exactly what you asked me to do. Thank you very much. I think now it is working properly 🙂
Please check the attachment for this discussion and update me if you realize anything wrong. Thank you again

Yes I faced the same problem with OOK. Actually, I got BER 0.028; which is still not good enough
Please check the attached file for OOK screenshot
