  • Abstract
    General high-resolution smoothing techniques for estimating deterministic sinusoidal frequencies from short-record noisy data are presented. Symmetric smoothings are proven to provide conjugate reciprocal polynomial roots also in the noisy case and thereby eliminate spurious frequency estimates. In numerical simulations they provided the lowest threshold of any currently existing method
