摘要

针对QAhI调制的非线性通信信道,提出了一种新的预失真器设计方法。通过将信道非线性补偿作为不动点问题,利用收缩映射理论迭代确定& k点来实现预失真。所提出的预失真器的主要优点是计算简单,因为所有的处理单元都是等效的。

A New Predistorter Design Technique For Nonlinear Digital Communication Channels
This paper presents a nen- predistorter design technique for a nonlinear communication channel with QAhI modulation. The predistortion is accomplished by considering the compensation of the channel nonlinearities as a fixed point problem, and determining the &Ked point iteratively using contraction mapping theory. The main advantage of the proposed predistorter is its computational simplicity in the sense that all the processing units are equivalent.
