Machine Learning-Aided Piece-Wise Modeling Technique of Power Amplifier for Digital Predistortion

We propose a new power amplifier (PA) behavioral modeling approach, to characterize and compensate for the signal quality degrading effects induced by a PA with a machine learning (ML) aided piece-wise (PW) modeling approach. Instead of using a single pruned Volterra model, we use multiple small-siz…
