摘要

It is proposed that the weighted-mean estimator of the Allan variance be used as an optimal estimator in measurements of the frequency instability of a particular signal by means of a multi-channel measurement system. The article presents an algorithm for numerical selection of the weight actors for an arbitrary number of signals used in the measurement that makes it possible to minimize the dispersion of the weighted-mean estimator. It also presents results from an analysis of analytic expressions and a numerical simulation based on the proposed algorithm.
