Abstract EN
The DFT-based frequency estimations have inherent limitations such as spectral leakage and picket-fence effect due to asynchronous sampling.
This paper focuses on comparing the windowed interpolation FFT (WIFFT) and quasisynchronous sampling algorithm (QSSA) for frequency estimation.
The WIFFT uses windows to reduce spectral leakage and employs interpolation algorithm to eliminate picket-fence effect.
And the QSSA utilizes quasisynchronous weighted iterations for frequency estimation.
The accuracy and time complexity of WIFFT and QSSA are theoretically studied.
Computer simulations of frequency estimations with noise and fluctuations by using WIFFT and QSSA are performed.
Simulations results show that the wideband noise sensitivity of QSSA is lower than that of WIFFT.
However, the WIFFT exhibits less time complexity than QSSA.
