Abstract
A computationally efficient algorithm based on the linear prediction property of sinusoidal signals is proposed for the direct estimation of the frequency of a real tone in white noise, assuming that the noise variance is available. The convergence behaviour and variance of the estimated frequency are derived and the ability of the method to track time-varying frequencies is demonstrated
