Abstract Frequency estimation, one of the key technologies in wireless communication and radar science, has been extensively and deeply studied by scholars. Based on a detailed frequency estimation characteristics analysis of two existing algorithms (the fixed Quinn algorithm and the A&M algorithm), this paper proposes a new and improved high-precision frequency estimation algorithm. The proposed algorithm is a two-step estimation. In the first step, we use the fixed Quinn algorithm to calculate coarse frequency errors, and in the second step, we use the results from the first step as the initial iteration in the A&M algorithm. After the first iteration, we obtain the precise frequency errors, and finally, we obtain the frequency estimate value. Through simulation experiments on MATLAB, the experimental results verify that the improved algorithm greatly enhances the estimation accuracy compared to the fixed Quinn algorithm and the A&M algorithm; moreover, the improved algorithm has excellent anti-noise performance and stronger algorithm robustness.
