OFDM achieves high spectral efficiency in wireless communication systems. However, it is difficult ti achieve high power efficiency because of its large PAPR. Envelope Pulse-Width Modulation (EPWM) transmitters have been proposed to obtain high power efficiency for the amplification of OFDM signals....
