A Nonlinear Predistortion Method Based on Taylor Series of HPA Distortion Model

本文提出一种高功率放大器非线性校正方法。它采用预失真技术,消除HPA失真模型的Taylor表达式中产生非线性的奇次方项,实现HPA的非线性校正。仿真结果表明,较好地补偿了HPA的非线性失真。

This paper presents a new nonlinear predistortion method of high power amplifier（HPA）. It uses preditortion technique to counteract the odd orders of Taylor series, which cause the nonlinear distortion in HPA distortion model. Simulation shows that it effectively compensates the nonlinear distortion of HPA.
