Open Access Simple and Accurate Bias and Variance Expressions of Some Instantaneous Frequency Estimators including the DESAs
Sewim Hazal Uz , Erdoğan Dilaveroğlu
3rd International Symposium on Innovative Approaches in Scientific Studies (Engineering and Natural Sciences) Vol. 4 pp. 537–540 2026
Instantaneous estimation of the frequency of a real sinusoid in noise from a small number of data samples is an important problem in the signal processing area. Several frequency estimators are proposed for this problem in the literature. I…
