Two Points Interpolated DFT Algorithm for Accurate Estimation of Damping Factor and Frequency
Kai Wang, He Wen, Li Xu, Lanlan Wang
Abstract
This letter proposes a two-points non-iterative IpDFT algorithm for parameter estimation of the damped real-valued sinusoidal signal, which is named as the I2pNDFT. Both long- and short- range leakages are compensated to estimate the parameters accurately. Simulation results prove the effectiveness of our methodmagenta, compared with other IpDFT methods.
