OFDM is widely used for mobile communications because it has high spectral efficiency and robustness against multipath fading. However, it has high PAPR and vulnerable to nonlinear distortion because of its multicarrier structure. Thus, it is difficult for current power amplifiers to amplify the OFDM signal with high power efficiency and good linearity. To address these issues, envelope pulse-width modulation (EPWM) transmitter has been proposed and improved with the amplitude noise compensating (ANC) technique, suppressing the quantization noise from the transmitter. In this paper, 3rd order delta-sigma modulator with null-response frequencies is employed in ANC-EPWM transmitter. It is shown that the 3rd order delta-sigma modulator provides sufficient performance for ANC-EPWM transmitter. |
