Hi…I am designing a polarisation division multiplexing based OFDM- free space optical communication system. The range of FSO link is 1 km with attenuation of 1.02 db/km attenuation only. But I am facing following problems:

1) I am not getting the desired bit error rate performance.It is very poor at link range of 1 km with attenuation of 1.02 dB/km.
2) No constellation diagram also for the system.

I am attaching the schematic for reference. I am using trial version of optisystem 17.

Thanks

      Hello Harjeevan,
      You need to send your project as a zip file to my email at ahmad.atieh@optiwave.com. I’ll check it for you in the next few days.
      Regards,
      Ahmad
