ITERATIVE PROCEDURE FOR REAL SINGLE-TONE FREQUENCY ESTIMATION
Liviu Toma, Aldo De Sabata, R. Pazsitka · 2009
We propose a simple, iterative procedure for the frequency estimation of a real sinusoid corrupted by additive, white noise, based on a combination of a known low-complexity method and filtering. We obtain mean square errors close to the Cramer-Rao lower bound, for relatively low signal-to-noise ratios in a few iterations, with a reasonable increase in computation complexity.
