VLC (Visible Light Communications) have been recently proposed as a new form of wireless communications. The VLC advantages are its usage of the spectrum of visible light which is not licensed; additionally, it gives high data rates, protects the user against espionage and does not suffer from interference of the electromagnetic spectrum. One of the main techniques used in VLC is HACO-OFDM (Hybrid Asymmetrically Clipped Optical - Orthogonal Frequency Division Multiplexing), which offers a high spectral efficiency. However, one of its main problems is its high PAPR (Peak-to-Average-Power Ratio). This article presents a study and simulation of Clipping, CE-POCS (Constellation Extension – Project Onto Convex Sets), OPS (Orthogonal Pilot Sequences) and SAP (Simple Amplitude Predistortion) techniques for the reduction of the PAPR in HACO-OFDM systems. The simulation results show that the SAP technique gives the best results in PAPR reduction without significant degradation in the BER (Bit Error Rate).
