Abstract
Official abstract text for this publication.
An approach facilitates synchronization by providing: (i) a method to analyze the two-satellite synchronization problem in time-frequency domain; and (ii) a two-stage estimation method to accomplish timing and frequency synchronization. The embodiment facilitates satellite diversity. The embodiment applies to a system involving two or more geosynchronous satellites.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: determining, by a processor of a communications device, a timing and a frequency for a data transmission associated with a communications terminal over a channel within a beam of a first satellite of a communications network, wherein the determinations of the timing and frequency for the data transmission over the channel of the first satellite are based on a first position within the beam of the first satellite; determining, by the pr…
