| Abstract: | For the high peak-to-average power ration （PAPR） of optical orthogonal frequency division multiplexing （O-OFDM） system, the main schemes and their strengths and weaknesses are introduced, including pre-distortion techniques, coding techniques, and probability techniques. The principles of clipping and PTS algorithms are expounded. In addition, their PAPR reduction validity is analyzed by simulation. |
