Behavioral modeling and digital predistortion of Power Amplifiers with memory using Two Hidden Layers Artificial Neural Networks

This paper presents a novel Two Hidden Layers Artificial Neural Networks (2HLANN) model for behavioral modeling and linearization of RF Power Amplifiers (PAs). Starting with a feedback loop principle model of a PA, an appropriate neural networks structure is deduced. This structure was then optimized to form a real valued and feed-forward 2HLANN based model… CONTINUE READING
