摘要

目前有许多数字基带预失真器，用于克服功率放大器对宽带信号的非线性和记忆效应。基于查表的Hammerstein预失真器就是其中的一种，与其他预失真器相比具有显著的优势。本文提出了一种基于查找表的Hammerstein预失真器系数提取的迭代算法。建立了ADS仿真试验台，对预失真器和算法进行了验证，仿真结果表明了算法的良好性能。

A coefficients extraction algorithm for LUT-based Hammerstein predistorters

There are many digital baseband predistorters, which are used to overcome the nonlinearity and memory effect of power amplifier for wideband signals. Look-up table-based Hammerstein predistorter is one of them and has remarkable advantages comparing with the others. In this paper, an iterative algorithm is proposed for extracting the coefficients of the look-up table-based Hammerstein predistorter. An ADS simulation testbed is built to verify the predistorter and algorithm, and the simulation results demonstrate the good performance of our algorithm.
