Hello.. I want to ask for a favor to check what’s wrong with my project.
I think the constellation diagram is fine but for BER, the requirement is at least 10^-9..but i did not get that value..i already tried increase the sequence length until the simulation got stuck..please help me..TQ

      Hello,
      I’ve noticed that the symbol rate is not correct. Since you use QAM, then the symbol rate must be bit rate/2. Also, you need to set the (Number of prefix points) in OFDM components to 0.
      If you need to discuss further, please email me at ahmad.atieh@optiwave.com.
      Regards,
      Ahmad
