Multi-carrier systems such as Orthogonal Frequency Division Multiplexing (OFDM) require linear amplification and have low power efficiency because of high peak-to-average power ratio (PAPR). In an Envelope Pulse-Width Modulation (EPWM) transmitter, the envelope component of a linear modulation wave...
