      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
