Different circuit‐level approaches to analyze the effects of nonlinear distortion on coded division multiple access (CDMA) wireless communication systems are studied in order to predict spectral regrowth at the output of a nonlinear device. Measurements of a simple MESFET amplifier tested with a W‐CDMA waveform are satisfactorily compared with the simulated results. © 2004 Wiley Periodicals, Inc.
