DPD und PA-Modellierung

KI zur Modellierung von digitaler Vorverzerrung und Leistungsverstärkern

Modellieren Sie einen Leistungsverstärker (PA) mithilfe eines neuronalen Netzes. Um die Effekte von Nichtlinearitäten bei einem Leistungsverstärker auszugleichen, können Sie ein neuronales Netz verwenden, um eine digitale Vorverzerrung (DPD) an das Eingangssignal anzulegen.
