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.
