Based on the linear prediction property of sinusoidal sig nals and weighted least squares, an efficient and computa tionally simple frequency estimator of a single real damped sinusoid in the presence of white noise is devised. Com puter simulations are shown to confirm the effectiveness of the proposed algorithm by comparing with Cram´er-Rao lower bound for different frequencies, observation lengths and signal-to-noise ratio conditions.
