%X The digital predistortion is a cost-effective way to the linearize power amplifiers. Memory polynomial is one of the most popular DPD models. However, these models cannot get a good compromise between accuracy and complexity. The author proposes a feedback-based model to characterize DPD. The model not only uses the input information, but also uses the past output information. Simulations show that the model can linearize the magnitude and phase nonlinearity of power amplifiers more effectively.
