Linearizing Power Amplifiers Using Digital Predistortion, EDA Tools and Test Hardware
This article presents a method for power amplifier linearization known as baseband adaptive digital predistortion. Using an EDA software package with both DSP (Digital Signal Processing) and RF capabilities, connected to a vector signal generator and a signal analyzer, this hardware/software connected system allows an actual hardware power amplifier to be optimally linearized for a specific wir...
متن کاملFPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects
Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...
