Abstract

In order to improve the nonlinear problems of power amplifier, this paper discussed about the nonlinear characteristic of power amplifier without memory and put forward a kind of new pre-distortion model. The MATLAB simulation process was being used to obtain the input and output amplitude curves, and calculated the normalized mean square error NMES and error vector magnitude EVM, the results show that the power amplifier linearization improved after pre-distortion processing.
