Orthogonal Frequency Division Multiplexing (OFDM) is an effective parallel multi-carrier transmission scheme. However, this technique has one weakness of a higher transmission signal Peak to Average Power Ratio (PAPR) when the signal is transmitted. To reduce the impact of High Power Amplifier (HPA) nonlinearity on OFDM system, this paper proposes the combination of improved clipping and filtering method and based on digital pre-distortion lookup table reduce the peak to average ratio of OFDM and improve the BER performance of the power amplifier in pre-distortion system and the effectiveness of HPA. The simulation results show there is a certain relationship between the PAPR reduction techniques and HPA linearization techniques.
