An Efficient Technique for Reducing Papr of OFDM System in the Presence of Nonlinear High Power Amplifier
By
Progress In Electromagnetics Research C, Vol. 2, 233-241, 2008
Abstract
Peak to Average Power Ratio (PAPR) is one of the serious problems in any wireless communication system using multi carrier modulation technique like OFDM, which reduces the efficiency of the transmit high power amplifier. In this paper, proposed scheme will be introduced that combine interleaving method with peak windowing. Simulation results show that our technique simultaneously decrease Bit Error Rate (BER), reduce the PAPR by 3.5 dB and improve out-of- band radiation, in presence of nonlinear power amplifier model.
