Özet

The bias and mean square error (MSE) analysis of the frequency estimator suggested in [1] 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.
