Abstract
Spectral regrowth of a code division multiple access (CDMA) signal passed through a weakly nonlinear circuit are analyzed using power series and statistical method The method yields an analytical expression for the autocorrelation function of the output signal as a the statistical function of the input signal transformed by a behavioral model of the amplifier. It provides helpful predictions of inter-modulation in wireless communication systems with nonlinear distortion effects. This method for the estimation of spectral regrowth for a CDMA signal passed through a nonlinear power circuit have been used in the design of a transceiver for CDMA communication systems.
