LED based OFDM – VLC Model working Problem

[Md Towfiqur Rahman]

Hello
I am Towfiq working on VLC (Lifi) projects. I made a QAM-OFDM based Visible light communication model but could not get the QAM constellation. Please, I need your help where is the problem. My think OFDM block has some problem for equalizing OFDM subcarrier so that SER and EVM are always high in LED-based VLC model.using LD (laser diode) is quite ok but using LED is a big problem. our LED in DD-OFDM model can’t constellation as well as BER is always very high. I attached here my model please have a look and try to help.
Please anyone can help. !!
