Abstract
An algorithm for accurate estimation of the carrier frequency, which is optimal by the criterion of the min-imum mean square error, is developed which is implemented using relatively short sync combinations distributed over the duration of the packet. The results of the dependence of the accuracy of estimating the carrier frequency on the level of channel noise are presented. Analytical expressions are obtained for an accurate estimate of the frequency and phase errors obtained on the basis of sufficiently short sync combinations. The results of simulation are demon-strated. The research results can be used in satellite radio links with packet data transmission.
