Modélisation de la prédistorsion numérique et d’amplificateurs de puissance
Modélisez un amplificateur de puissance (PA) avec un réseau de neurones. Pour compenser les effets des non-linéarités dans un amplificateur de puissance, vous pouvez utiliser un réseau de neurones afin d’appliquer une prédistorsion numérique au signal d’entrée.Pour une description du workflow, veuillez consulter AI for Digital Predistortion Design (Communications Toolbox).
