The envelope pulse-width modulation (EPWM) transmitter has been proposed to address the issue of low power efficiency in the linear amplification of multicarrier signals such as the OFDM. However, the delta-sigma (Σ-Δ) modulator in the EPWM transmitter generates quantization noise that degrades sign...
