This article presents a method for power amplifier lineariza-tion known as baseband adaptive digital predis-tortion. Using an EDA software package with both DSP (Digital Signal Processing) and RF capabilities, connected to a vector signal generator and a signal analyz-er, this hardware/software connected system allows an actual hardware power amplifier to be optimally linearized for a specific wireless transmission standard.
