Abstract :
The carrier frequency offset estimation algorithm proposed by Fitz (1994) has low work threshold and high accuracy, but it has a narrow estimation range, which limits its application. By analyzing the algorithm of Tretter and Kay, we give an improved Fitz carrier frequency offset estimation algorithm. Simulation show the improved algorithm has a large carrier frequency estimation range, about ±50% of the symbol rate. At the same time, the algorithm has the same accuracy and work threshold as the original Fitz algorithm.
