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

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
