Abstract

Signal predistortion is suitable for linearizing amplifier nonlinearity in high speed wireless applications. Volterra series provide an input-output relationship for nonlinear system with memory. The paper presents a new digital predistortion approach for the power amplifier linearization when we use the Volterra series for dynamic nonlinear modeling of the power amplifier comportment. The major advantage of the method is that the predistorter minimizes the total distortion power instead of reducing one specific intermodulation product by linearizing the bandpass response of the amplifier
