A comparative analysis of behavioral models for RF power amplifiers
TL;DR: The models with memory, PH, and RBFNN, showed better cross-validation performance, in terms of lower model errors, than a static polynomial for the hardest cross validation of the 2G PA.

Behavioral modeling of nonlinear RF power amplifiers considering memory effects
Hyunchul Ku,J.S. Kenney +1 more
TL;DR: In this article, the authors proposed a behavioral model to treat memory effects in nonlinear power amplifiers (PAs) by augmenting the memory polynomial model with a sparse delay tap structure that reduces the parameter space required for accurate model identification.
