What is PAPR Reduction in VLC Using DFT Precoding about?

This paper presents a novel modulation technique called double precoded O-OFDM (DP-OOFDM) that combines DFT precoding and GMSK pulse shaping to reduce the peak-to-average power ratio (PAPR) in optical OFDM systems for visible light communication (VLC). The proposed method aims to enhance PAPR, symbol-error-rate, and power-saving performance while addressing the computational complexity associated with DFT precoding. The results indicate that DP-OOFDM outperforms traditional DFT-precoded O-OFDM and ACO-OFDM
