Publication number: 20210227046Abstract: A method and system for delivering services to terminals and associated edge devices in a satellite communication system. A network node remotely creates at least one service appliance within a terminal of the satellite communication system and customer premise equipment (CPE) connected to the terminal. Containerized applications are then transmitted from the network node to the service appliance. The service appliance subsequently executes the containerized application using hardware resources of the terminal and CPE. Usage of the containerized application can also be monitored.Type: ApplicationFiled: January 22, 2020Publication date: July 22, 2021Applicant: HUGHES NETWORK SYSTEMS, LLCInventors: Chi-Jiun SU, Neal BECKER, Lin-Nan LEE, Stan KAY

Patent number: 9614554Abstract: An approach for improved compensation for nonlinear distortion in multicarrier satellite systems is provided. Source reflecting encoded and modulated sequences of source data symbols are received. Each source signal is predistorted, and a transmit filter is applied to each predistorted source signal. Each filtered signal is translated to a carrier frequency, and the translated signals are combined into a composite signal for transmission via a multicarrier transponder. The final predistorted version of each source signal is generated via an iterative process of a number of stages, wherein, for a given stage and for each source signal, the process comprises: receiving a prior predistorted version of each source signal from a preceding stage; processing each prior predistorted source signal based on all of the received prior predistorted source signals, wherein the processing is performed based on a characterization of one or more characteristics of the multicarrier satellite transponder.Type: GrantFiled: June 12, 2015Date of Patent: April 4, 2017Assignee: Hughes Network Systems, LLCInventors: Bassel Beidas, Rohit Iyer Seshadri, Neal Becker

Patent number: 9264675Abstract: A system for a multiplexing scheme for wideband signals in a communications system is provided. A codeblock of a multiplexed datastream is decoded. The codeblock includes a flag indicating whether the codeblock contains a timeplan, signifying a multiplexing structure of the datastream. A determination is made whether the flag indicates the presence of the timeplan, and, if so, the timeplan is acquired. In response to a determination that the codeblock does not contain the timeplan, a subsequent codeblock is determined, and decoded. Each codeblock includes an indicator of a sequence position of the codeblock within a group of codeblocks of the datastream. The subsequent codeblock is determined based on one or more of a decode rate of the processor device and the sequence position indicator. A determination is made whether the flag of the subsequent codeblock indicates the presence of the timeplan, and, if so, the timeplan is acquired.Type: GrantFiled: December 12, 2011Date of Patent: February 16, 2016Assignee: Hughes Network Systems, LLCInventors: Yezdi Antia, Dave Roos, Neal Becker

Publication number: 20150280757Abstract: An approach for predistorting signals to be transmitted via a multicarrier satellite transponder to account for inter-symbol interference. Multiple source signals are received. A transmit filter model is applied to each source signal to generate a respective filtered signal. Each filtered signal is translated to a carrier frequency, and the translated signals are summed to generate a composite signal. A common non-linearity model is applied to the composite signal to generate a model transmit signal. The transmit signal is translated to generate a receive signal estimate for each of the filtered signals. A receive filter model is applied to each receive estimate to generate a filtered estimate. Each filtered estimate is subtracted from the respective source signal to generate an error sequence. A fraction of the error sequence is added to the respective source signal to generate a predistorted signal for transmission via a multicarrier satellite transponder.Type: ApplicationFiled: March 31, 2015Publication date: October 1, 2015Inventors: Bassel BEIDAS, Neal BECKER

Patent number: 8879674Abstract: An approach is provided for correlation of a signal over time and frequency. The signal is correlated with a bit sequence over time instances and certain frequency offsets, wherein sub-segments of the signal are correlated with sub-segments of the bit sequence to generate a correlation factor associated with each signal sub-segment. The correlation factors are coherently combined to generate a final correlation factor, wherein a respective phase shift (for each frequency offset) is applied to each correlation factor to generate a set of frequency adjusted correlation factors, and the frequency adjusted correlation factors of a respective set are combined to generate the final correlation factor over the signal sub-segments, resulting in the matrix of final correlation factors over time and frequency. A signal parameter estimation is performed, based on the matrix of final correlation factors, to determine a highest correlation value for the signal over the frequency offsets.Type: GrantFiled: April 10, 2013Date of Patent: November 4, 2014Assignee: Hughes Network Systems, LLCInventor: Neal Becker
