Abstract
Spectral regrowth of a CDMA signal and in-channel distortion causing the gain compression or expansion are analyzed using the power series and statistical theory. The proposed time-domain model of the CDMA signal is shown to give more accurate distortion estimates than the widely used narrow-band Gaussian noise assumption. The model was also used to show the difference between statistical properties of the CDMA signal and the Gaussian noise
