Problem with VLC-OFDM system
I want to design an indoor based communication system. I am working on a VLC-OFDM system. I used the FSO OFDM QAM file of Optisystem 17.1 and replaced the laser with a LED. Hoping to get a good BER in range of 1 to 10 meters but I am not able to. BER test set always shows extremely high values like 0.5. Could anyone please help me with my project, I am fairly new to the software and still learning it.
The file is attached. I would really appreciate some help.
Thanks in advance
