OFDM modulation produces higher Peak Average Power Ratio (PAPR) whenever the carriers in OFDM symbol add synchronously in the time domain resulting in higher signal power. This high power saturates the power amplifier placed in the RF section res

m-file调查高功率放大器的影响，channelnoise在ofdm信号，当时介绍卡由于一个paprreductionmethod减少hpa效果。-m-file investigation of high-power amplifier, channelnoise in ofdm signal, when introduced to reduce card due to a paprreductionmethod hpa effects.

In Modulation schemes such as OFDM transmitter time domain signal will have higher PAPR, which leads to various distortions in the transmitter chain and degradation of system performance i.e. BER/PER. Also requires highly linear power amplifier which
