摘要
在分析 PLL 和 FLL 环路各自优点的基础上,提出了一种 FLL/PLL 相结合的载波跟踪方法,分析了热噪声及载体动态性对载波跟踪环路的影响,得出了环路设计的最佳带宽。理论分析和仿真结果表明,该方法能快速地、精确地实现载波的跟踪。
Based on analyzing the advantages of PLL and FLL,a new method of carrier tracking,which is combining FLL with PLL is presented in this paper.At the same time,this article analyze the effect of thermal noise and vehicle dynamics on the carrier tracking loop,and give the optimal handwidth of the carrier tracking loop .The analysis and simulations show that this method could realize the carrier tracking quickly and precisely.
