@article{jang_walker_gard_steer_2006, title={Capturing asymmetrical spectral regrowth in RF systems using a MultiSlice behavioral model and enhanced envelop transient analysis}, volume={16}, ISSN={["1099-047X"]}, DOI={10.1002/mmce.20160}, abstractNote={Nonlinear distortion in RF and microwave systems results in spectral regrowth of digitally modulated signals. The distortion above and below the main channel can be at different levels and this is attributed to baseband effects. This article presents a new multislice behavioral‐model architecture that captures this asymmetry and can be implemented in a variety of circuit simulators, including SPICE, harmonic balance (HB), envelope transient (ET), and system simulators. The work is experimentally validated using an HBT power amplifier at 2.5 GHz driven by a WCDMA signal. The model is used with envelope transient circuit simulation which is enhanced to accommodate an arbitrary baseband transfer function. © 2006 Wiley Periodicals, Inc.

The co-simulation of low-pass equivalent behavioral models with circuit based models is addressed by simulating the overall wireless communication path. Several application examples are considered, in particular, the modeling of complete wireless communications circuits and systems incorporating the radio channel model.}, number={2}, journal={IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES}, author={Carvalho, NB and Pedro, JC and Jang, WH and Steer, MB}, year={2006}, month={Feb}, pages={572–579} }
