Detection of independent timing jitter in sinusoidal measurements

Two detectors of symmetrically distributed independent timing jitter in a data record composed of a complex harmonic in additive white Gaussian noise are proposed. The proposed detectors are computationally efficient and, although they are formulated using asymptotic results, they may be effectively used with small sample lengths under a wide range of conditions. The performances of the detectors are analysed using simulations and theoretical results.
