MUMBAI, India, Aug. 29 -- Intellectual Property India has published a patent application (202517076604 A) filed by Viasat, Inc., Carlsbad, U.S.A., on Aug. 12, for 'methods and apparatuses for diversity transmission in a satellite-based communication system.'
Inventor(s) include Petranovich, James E.; Buer, Kenneth V; and Fabbri, Simon.
The application for the patent was published on Aug. 29, under issue no. 35/2025.
According to the abstract released by the Intellectual Property India: "A satellite communication system uses a plurality of optical feeder links between its ground segment and its space segment and employs spatial diversity transmission, which splits individual user data streams into sub-streams sent across two or more of the optical feeder links such that recovery of the full stream at the receiving end is possible despite impairments affecting individual feeder links over which the stream is split. Further, the system applies beamforming separately with respect to the feeder links, meaning that transmission time alignment is not needed between respective ones of the sub-streams. Spatial diversity transmission occurs in the forward direction or in the return direction or both and may be employed on a conditional basis and dynamically adjusted with respect to individual user terminals, groups of user terminals, or whole populations of user terminals."
The patent application was internationally filed on Jan. 17, 2023, under International application No.PCT/US2023/010920.
