Estudio y simulación de técnicas para reducir la PAPR en HACO-OFDM

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