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.
