Abstract

In a previous paper, a frequency estimator using only three Fourier coefficients was introduced, which has asymptotic variance of order T 3. In this correspondence, a similar technique of Rife and Vincent is shown to have asymptotic variance of larger order. A new estimator is introduced that has asymptotic variance less than 1.65 times the CRLB.
