To improve the efficiency of optical channel, the idea of Wavelength Division Multiplexing (WDM) was evolved in which multiple optical signals on different wavelength were sent through the fiber simultaneously. Later on, the Coherent Optical Orthogonal Frequency Division Multiplexing (CO-OFDM) has been introduced into WDM.

Peak to Average Power Ratio (PAPR) Minimizing Techniques for Helical Interleaved OFDM System
2017Orthogonal frequency-division multiplexing (OFDM) is a multi-carrier, multi rate, multi symbol, frequency division multiplexing transmission system. In which a single high data rate stream is divided in to a number of low data rate streams. High spectral efficiency due to orthogonal subcarriers is the major advantage of this system.

In this paper, two distortionless PAPR reduction techniques, Selected Mapping (SLM) and Partial Transmit Sequences (PTS), are compared in terms of PAPR reduction capability and computational complexity for equal number of candidate OFDM symbols. Using MATLAB simulation, it is shown that SLM outperforms PTS in PAPR reduction capability. For small values
