Abstract
Digital pre-distortion (DPD) used to linearize an RF power amplifier (PA) can achieve wide bandwidth distortion cancellation. The predistortion technique is one of the most effective linearization technique. Model-based DPDs also called polynomial based DPDs, are mostly used for the linearization of PA. For the memoryless system, the polynomial model can be used to model the predistorter. For memory system, the models such as Volterra series model, generalized memory polynomial model, Hammerstein model and Wiener model all are used to model the predistorter. DPD architectures can be classified into two types Indirect Learning Architecture (ILA) and Direct Learning Architecture (DLA).In this paper, a survey on different model digital predistortion used to linearize RF power amplifier in different works.
