Baseband Wiener Predistorter for Linearizing Power Amplifier

摘要

A new predistorter based on Wiener model to linearize power amplifier with memory effects is proposed. Because a zigzag-envelope δ-impulse sequence is used for training, the parameters of linear section and nonlinear section in the predistorter can be separately obtained easily. Simulation results demonstrate the predistorter behaves very well.
