Precoded-DC-Biased Optical OFDM system for Visible light communications

• Traditional OFDM techniques in VLC suffer from high PAPR and serious clipping distortion. In this paper, we propose a Precoded-DC-Biased Optical OFDM technique for VLC system. Numerical simulations are presented, proving substantial benefits in terms of PAPR and BER.
