Abstract
A theoretical approximation for the variance of Kay's weighted linear predictor frequency estimator is derived. From this expression, an ine quality describing the variance threshold of the estimator is found. T he window weights are then optimized to improve the variance. Numerica l simulations demonstrate that the variance approximations are valid f or medium to high signal-to-noise ratios or for large numbers of sampl es.
