Analysis of CDMA signal spectral regrowth and waveform quality

Spectral regrowth and waveform quality of a reverse-link CDMA signal passed through a weakly nonlinear circuit are analyzed using the power series and statistical methods. The analysis is based on a time-domain model of the signal that gives more accurate distortion estimates than the widely used Gaussian noise assumption. The model is also used to derive the probability density function of the CDMA signal to show its difference from that of the Gaussian noise.
