Abstract
This paper presents a comparative study on the suitability of using Hammerstein or Wiener models to identify the power amplifier (PA) nonlinear behavior considering memory effects. This comparative takes into account the operational complexity regarding the identification process as well as their accuracy to follow the PA behavior. Both identified PA models will be used to estimate a Hammerstein based predistorter in order to see which model combination provides better linearization results. In addition, two adaptive algorithms for predistorting both PA models are compared in terms of accuracy and converge speed.
