Abstract
Peak to average power ratio (PAPR) is one of the serious problems in any wireless communication system using multicarrier modulation technique like OFDM, which reduces the efficiency of the transmit high power amplifier. In this paper, we suggest a new scheme based on μ-law compander where the optimum value of μ is calculated. With the newly proposed scheme, the simulation results show that, the PAPR is reduced by 5.8 dB. Moreover, Eb/N0 is decreased by 6 dB at bit error rate (BER)=10-3 in the presence of nonlinear power amplifier.
