基于锁频环+FFT+锁相环的载波跟踪方法
Carrier Tracking Method Based on FLL+FFT+PLL
摘要
Abstract
Aiming at the problem that the traditional method is difficult to achieve the transformation from the carrier capture to the carrier tracking under the condition of low SNR,a method of carrier tracking based on FLL+FFT+PLL is presented.The method based on FFT can reduce the frequency offset when the tracking mode is transited from FLL to PLL,improving the success probability of transformation from the carrier capture to the carrier tracking.The principle of the proposed method is elaborated.The simulation results show that the success probability can reach up to 100% based on the proposed method.关键词
