Abstract
A modified frequency estimation method for use in the presence of additive complex white Gaussian noise is proposed. This method is basically an extension of Kay´s method, but includes the use of autocorrelation functions. It retrieves the frequency value from the optimal linear combination of the differenced phases of the autocorrelation functions. It yields a considerably lower variance threshold than Kay´s method while remaining unbiased and retaining the same frequency range
