| Abstract: | A rigorous approach of complex envelop on time domain was used to analyze RF power amplifier with the nonlinear distortion characteristics excited by CDMA signal and demonstrate the degradation of transmitted signal performance with the nonlinear characteristics in this paper. The method was based on the measured AM AM, AM PM features of RF power amplifier. The band pass nonlinearity theory and the digital signal processing techniques were applied |
