Joint Time and Frequency Offset Estimation for Clock Synchronization
Ferrandiz, Josep M.
Abstract: Timing data gathered from network traffic is fed into a Kalman filter designed to jointly estimate the clock offset and the clock frequency offset with respect to the time server. The method proposed builds a statistical framework for synchronization of computer clocks that allows a probabilistic interpretation of the quantities involved. The tests show that the filter performance is for all practical purposes optimal.
