HIGHLIGHTS
- who: LEI FAN and collaborators from the School of Information Science Engineering, Dalian Polytechnic University, Dalian, China have published the Article: Accurate Frequency Estimator of Sinusoid Based on Interpolation of FFT and DTFT, in the Journal: (JOURNAL)
- what: An accurate sinusoidal frequency estimation algorithm based on interpolation of FFT and DTFT is proposed in this paper.
- how: According to the DTFT definition the DTFT of z(n) at the location f is Zf= N -1 X z(n)e-j2u03c0fTn/N n=0 Let Zf0=e-ju03c6 Zf the following expression is obtained . . .
