Abstract :
In this paper, we analyze an algorithm devised for the frequency estimation of a real, noisy sinusoid, at low signal-to-noise ratios. The algorithm consists of a combination between a closed-form estimator and frequency selective filtering. We reveal its connection with the constrained notch filter approach. We calculate the asymptotic cost function and report results on bias and variance.
