Abstract :
We address the problem of the frequency estimation of a sinusoid embedded in additive, white noise, by using a combination of statistical estimators and filtering. We test a low-complexity, iterative algorithm, devised for low signal-to-noise ratios, that approach the Cramer-Rao lower bound in a few iterations. We calculate the asymptotic cost function and evaluate the bias.
