  This is a template file.
  How can I get a better eye diagram for this system?
  After simulation , It results in 0 Bit error rate, why?

  You should not try evaluating the OFDM systems with eye diagrams. Use BER TEST SET instead to notice values for number of error bits.
  Also the 0 BER is because for very long sequence lengths in case of OFDM. 0 BER means error free communication.

  for more details goto
  
  LTE signal OFDM (64QAM)
  
  It will help you clarifying your doubts

  Thank you Abhishek Shrama for your response.
  
  1. You should not try evaluating the OFDM systems with eye diagrams. can I ask why?
  2. how can I measure SNR for this tempalte?
  3. How can I add PMD paramter and fiber nonlinearity in this template?
