Polarization Division Multiplexing based OFDM-FSO System
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.
