Abstract :
In this paper we have tested different Volterra-based behavioral models for wideband power amplifiers (PAs) using an OFDM probing signal. Two PAs have been widely characterized and the measured output complex envelopes have been compared with the model predictions in terms of the normalized mean square error, spectral regrowth and the adjacent channel error power ratio.
