And Performance

Asymmetrically clipped optical OFDM is modulation techniques with high optical power efficiency, but it has the high peak-to-average power ratio (PAPR). In atmospheric laser communication system, the high PAPR will not only have an impact on system performance, but also have damage to the human eye or skin. To solve high PAPR of asymmetrically clipped optical OFDM system, some solutions that have been proposed for wireless OFDM system have been studied. But all these methods can not be directly applied to the asymmetrically clipped optical OFDM system. In this paper, these methods have been adapted, and performance of these methods is analyzed. The simulation results show that the adapted methods can well reduce the PAPR of asymmetrically clipped optical OFDM system.
