摘要
随着移动通信中线性调制方法的出现 ,功率放大器的线性化已成为一个重要的研究课题。迄今人们已研究出了多种对放大器进行线性化的技术和方法 ,然而理论分析和计算机仿真及实验结果显示[3 -7] ,预失真线性化技术是最理想的对放大器进行线性化的技术。提出了一种预失真线性化技术的新方法 ,对该方法的组成原理作了较为详尽地论述 ,并给出了实验仿真结果。
Linearization of power amplifiers has become an important issue, with the advent of linear modulation methods in mobile communication. Various technologies of linearizing amplifiers have been developed, but the theoretical analysis and the results of simulation and experiment show that the predistortion linearization technology is the most perfect technology. This paper puts forward a kind of new method of predistortion linearization technology, discusses the principle of the technology in detail, and presents the simulation results.
