Abstract
This paper represents a new modified algorithm for modeling High Power Amplifier (HPA) based on wiener model for wideband applications such as OFDM. Meanwhile the measurement of memory effects is done. Next, novel approach for estimating parameters of adaptive predistorter (PD) based on Hammerstein represents. Finally the assessment of the new methods for PA and PD modeling are confirmed by computer simulation.
