Abstract

In this paper, a novel method combined the linear and nonlinear methods, named as partial transmit sequence followed by clipping (PTS-Clipping), is proposed to reduce the peak-to-average power ratio (PAPR) of radio over fiber and orthogonal frequency division multiplexing (ROF-OFDM) system. The main technique of this method is clipping the processed signal whose probability of the peak value has been reduced by PTS technique. Then the PAPR value will be further reduced. It will bring in slight change to the BER performance between with and without clipping. We know that both the ROF and OFDM techniques are key issues of the next generation network. Reduce the PAPR of OFDM is a necessary work. The simulation results show the feasibility of this method.
