Abstract
The paper analyzes some methods estimating the frequency of a sinusoid. A method of using the connotative amplitude and phase information of DFT is presented. The method overcomes the bar-effect when using DFT to estimate the frequency. And the method also improves the estimation accuracy of the frequency. Simulation results demonstrated the validity of the method.
