Patent number: 11968030Abstract: Described herein are systems, devices, and methods that improve network communication on a high-latency network by using a low-latency network to manage return-link bandwidth. Embodiments of the systems described herein include a user terminal that is communicatively coupled to a high-latency network and a low-latency network. The user terminal is configured to communicate with a gateway routing device over the low-latency network. The user terminal requests return-link bandwidth and the gateway routing device provides a transmission schedule to the user terminal over the low-latency network. The user terminal can be configured to transmit a message over the high-latency network using the scheduled return-link bandwidth.Type: GrantFiled: August 26, 2021Date of Patent: April 23, 2024Assignee: VIASAT, INC.Inventors: James E.

Publication number: 20230134051Abstract: Systems and methods are described that enable user terminals to eliminate or reduce the number of dummy bursts (or bursts with no data) they send. The systems and methods use two burst detectors, a first burst detector that analyzes the physical structure of the signal, and a second burst detector that analyzes the informational structure of the signal. Output from the first burst detector can be used to control operation of a signal decoder that decodes received signals. The second burst detector analyzes output from the signal decoder to determine the second burst indicator. In other words, the first burst detector can be implemented prior to decoding the received signal to provide a first estimate related to the presence or absence of a burst. This can then be used to limit the amount of processing performed by the signal decoder.Type: ApplicationFiled: April 6, 2021Publication date: May 4, 2023Applicant: VIASAT, INC.Inventors: Kaushik CHAKRABORTY, Srikar POTTA, Aniruddha DAS, James E.

Publication number: 20230118482Abstract: Schedulers that allocate resource grants on a slot-by-slot basis within a scheduling epoch or frame can create a front-loading effect where allocations occur more frequently in slots earlier in frames. To address these and other issues, systems and methods are disclosed for scheduling resource grants in a network to improve network transmit power profiles. For example, a scheduler is configured to randomize the order of slots in a scheduling epoch or frame, with different randomizations for different schedulers, to more evenly distribute slots with resource grant allocations to prevent or reduce a front-loading effect. As another example, the scheduler is configured to randomize start times of resource blocks within a slot to prevent or reduce the front-loading effect.Type: ApplicationFiled: April 6, 2021Publication date: April 20, 2023Applicant: VIASAT, INC.Inventors: Kaushik CHAKRABORTY, Srikar POTTA, Aniruddha DAS, James E.

Patent number: 8737420Abstract: There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. Each of the stations is configurable to generate one or more tone maps for communicating with each of the other stations in the powerline network. Each tone map includes a set of tones to be used on a communication link between two of the stations. Each tone map further includes a unique set of modulation methods for each tone. Each of the stations is further configurable to generate a default tone map for communicating with each of the other stations, where the default tone map is valid for all portions of a powerline cycle. Each of the stations is further configurable to monitor its bandwidth needs and to request additional bandwidth from the central coordinator.Type: GrantFiled: July 24, 2006Date of Patent: May 27, 2014Assignees: Sigma Designs Israel S.D.I.

Patent number: 8644341Abstract: A MAC layer protocol that converts packets into a data stream is presented. The protocol layer accepts packets (like Ethernet packets) and converts them into blocks. The packets may be segmented into multiple hocks and multiple packets or packet fragments may be contained in a block. The blocks contain information for reassembling the data. All blocks may be exactly the same size and format, with the same coding. This allows blocks to be precisely recovered even when some of the bits on the stream have errors on them. The blocks may be interleaved and coded. Each block may be decoded independently of other blocks. The blocks may be numbered, so an ARQ mechanism may request that any missing blocks be resent without asking for a whole packet to be resent. The data stream may be passed to a physical layer like an OFDM or WOFDM stream of data.Type: GrantFiled: September 24, 2004Date of Patent: February 4, 2014Assignee: Sigma Designs Israel S.D.I.

Patent number: 8553706Abstract: There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. The central coordinator is configurable to transmit a beacon at an interval based on a phase of a powerline cycle. The interval of the beacon can be substantially equal to two periods of the powerline cycle. The interval of the beacon includes a reserved region including a persistent allocation region and a non-persistent allocation region. The beacon also includes a broadcast message including a persistent schedule and a non-persistent schedule. The persistent schedule is valid for a current beacon period and a number of subsequent beacon periods as indicated by the beacon, while the non-persistent schedule is valid for a single beacon period. The persistent allocation region and the non-persistent allocation region are determined based on the persistent schedule and the non-persistent schedule, respectively.Type: GrantFiled: July 24, 2006Date of Patent: October 8, 2013Assignee: CopperGate Communications Ltd.Inventors: Neal Riedel, Yiorgos M.

Patent number: 8509315Abstract: Synchronization of data streams is enabled. Synchronized data streams may include compressed data streams. Conventional data compression components may be utilized to generate the compressed data streams. As an example, compressed digitized video and associated metadata may be synchronized in this way. Synchronization may be enabled based on causing data compression components to generate detectable data units. For example, patterns of data units having well characterized entropies may be passed through data compression components to generate detectable patterns of compressed data units.Type: GrantFiled: September 23, 2009Date of Patent: August 13, 2013Assignee: ViaSat, Inc.Inventor: James E.
