Hi Ranjeet Kumar,
Thank you for your kind response and I do agree with what you have mentioned “we could use this decoder in Dqpsk system”. In the DQPSK system receiver I am getting some excellent results but not in case of MSK and I noticed that in one of the post damian mentioned that in case of MSK signal it is a bit complex equation to design an exact MSK transmitted signal. So it would be better to expect some help from optiwave team. I have not tried using MATLAB code and make a component in optisystem as all the component property is nor wit us. so we need support from Optiwave team.
Regards,
Dhiman
