      Hi feras,

      According to your question, what do you exactly mean by “getting best result”? Are you working on decreasing BER, improving eye diagram or enhancing your transmission characteristics, i.e. maximum transmission length? Several discussions took place in our forum about your topic (please, see links below):

      @ Feras
      Greetings!.
      I hope your mentioning about”best results” is about getting high Q factor.
      As you are working on coherent optical OFDM you can check following discussions for reference:

      OPTISYSTEM OFDM Example


      http://www.dsplog.com/2012/01/01/symbol-error-rate-16qam-64qam-256qam/

      BER cannot measured for 16-QAM-OFDM direct detection

      You can also download the sample files from hot topics:

      for basic study of what parameters needs to be varied for best q factor ans minimum BER go through

        You are welcome, feras. I am glad that you have obtained the results by yourself. Self-learning is very beneficial!
