The envelope pulse-width modulation (EPWM) transmitter has been studied to address the power efficiency issue on the linear amplification of OFDM signals. However, the delta- sigma (Delta-Sigma) modulator in the EPWM transmitter generates quantization noise that degrades signal quality. In this pape...
