| Abstract: | Complex correlation method for estimating average frequency of signal is introduced in this paper. In order to reduce the influence of noise on the estimation error, the relationship between the sampling frequency and estimation error is analyzed. Optimal sampling frequency and experimental results of the estimation are also given. |
