Using clipping and filtering algorithm to reduce PAPR of OFDM system

Abstract-This paper describes the OFDM technology and its applications. Analysis the causes of PAPR in OFDM system, then the number of different sub-carrier under the conditions were simulated CCDF. Using clipping and filtering algorithm effectively reduces the PAPR of OFDM system, and the effect of reducing the PAPR and BER performance of the system were both made theoretical analysis and simulation. By analyzing the simulation results, show that the clipping and filtering algorithm than the direct clipping algorithm is more effective to reduce the PAPR of OFDM system.
