This article discusses several different implementations of Volterra series models, and performs a fair comparison between them using measured data and well known figures of merit. Among the implemented models, an approach that uses sub-sampling techniques together with Volterra series in a parallel cascade structure shows an improved performance compared to the other variations of Volterra series models. Based on the results, new trends in RF power amplifier behavioral modeling are suggested.
