Total Hadamard Variance: Application to Clock Steering by Kalman Filtering



David A. Howe, Ron Beard, Chuck Greenhall, Francois Vernotte, Bill Riley


The Total variance approach has been developed for increasing the confidence of the estimation of the classical Allan variance, particularly for large integration times. This method is based on a procedure involving extension of the original data. Recently, we showed how this approach may be applied to all classes of structure functions (i. e. variances) relevant to the time and frequency community.
