Digital Predistortion of Nonlieaner RF Power Amplifier with Memory Effects. This M code simulates a DPD technique linearization for a AB-class nonlinear HPA with memory effects. Here we consider a memory polynomial predistorter to modeling nonlinearity characteristics and memory effects of a HPA.Simulation procedures divided into three separate parts:1)Analog imperfection compensation for the direct upconversion transmitter2)Design a DPD based on a memory polynomial predistorter3)Performance ev
