摘要
作为通信系统核心器件的功率放大器的线性度直接影响了整个系统的通信质量,而前馈线性化技术综合性能较好,一直以来都是研究的热点。论文基于自适应前馈电路的原理,引入了一种改进的LMS算法,通过计算机软件仿真,表明该算法可以很好地改善系统的线性度。
The linearity of the power amplifier which is the key device of communication system affects the quality of the whole system, and feedforward linearization technology holds good comprehensive performance, so it has always been the research hotspot. A modified LMS algorithm which is based on the principle of the adaptive feedforward circuit is introduced. Through computer simulation software, it can he seen that this algorithm can improve the linearity of the system well.
