Decorrelation-based Piecewise Digital Predistortion: Operating Principle and RF Measurements

, 2019
In this paper, we propose a new closed-loop learning architecture for digital predistortion (DPD) with piecewise (PW) memory polynomial models. The technique is targeted specifically for power amplifiers (PAs) that exhibit strong nonlinear behavior and ...
