Orthogonal Frequency Division Multiplexing (OFDM) has emerged as a promising modulation technique for high speed optical systems as it reduces inter-symbol interference and offers high spectral efficiency. But it has an inherent drawback of high Peak to Average Power Ratio (PAPR) due to multiple subcarriers which makes it sensitive to non-linear effects. Different techniques have been proposed for PAPR reduction in literature. This paper presents the joint modified Sliding Norm Transform (SNT) combined with distortion based clipping technique for PAPR reduction in Optical OFDM systems.
