摘要

本文主要研究功率放大器的数字预失真线性化问题。提出了一种自适应系统仿真具有发射机缺陷(幅度不平衡、相位不平衡、直流偏置、模拟链延迟)补偿方法的数字预失真算法。介绍了这些方法,并讨论了它们的性能。

Digital Predistorion with Transmitter Imperfection Simulation
This paper is focused in the area of digital pre-distortion linearization of power amplifiers. It presents an adaptive system for simulation of digital predistortion algorithm with transmitter imperfection (amplitude imbalance, phase imbalance, DC offset, analog chain delay) compensation methods. These methods are presented and their performance is discussed.
