Cramer-Rao bound, frequency estimation, threshold effect
The bias and mean square error (MSE) analysis of the frequency estimator suggested in  is given and an improved version of the estimator, with the removal of estimator bias, is suggested. The signal-to-noise ratio (SNR) threshold above which the bias removal is effective is also determined.
