Abstract
Different circuit-level approaches to study the effects of nonlinear distortion on coded division multiple access (CDMA) wireless communication systems are analyzed. These techniques are used to predict spectral regrowth and baseband signal vector constellation at the output of a nonlinear device. To demonstrate and verify their capability, a simple MESFET amplifier has been tested with a W-CDMA waveform. The active device was widely characterized including the extraction of large-signal model parameters. Measurements were satisfactorily compared with the simulated results.
