VII. Conclusions
An effective technique to counteract HPA non linear
distortions has been presented. The study has pointed out some
aspects to considere in the future to improve the predistorter
performance by a more complex hardware which will be the obiect
of further investigations. Measuraments on the completed Itelco
Device will be available soon: a performance comparison between
the simulated device and the real one will be presented in a future
work.
