Publication number: 20170188317Abstract: Power spectral density in an aeronautical satellite communication system is controlled through the use of adaptive inroute selection and spreading. Once a communication session has been established between the aircraft and the satellite, environmental conditions and aircraft conditions are monitored to detect events capable of affecting transmit/receive properties during the communication session. A maximum allowable transmission output is determined based, at least in part, on governmental regulations and the conditions being monitored. One or more transmit parameters are adjusted during the time interval in order to maintain transmission output power of the aircraft terminal below the maximum allowable transmission output power.Type: ApplicationFiled: February 28, 2017Publication date: June 29, 2017Inventors: Bahman SALAMAT, Jack LUNDSTEDT, Yezdi ANTIA, Guy MONTGOMERY, John SCHMID

Patent number: 9391642Abstract: An approach for encoding a physical layer (PL) header of a PL data frame is provided. The PL header comprises sixteen information bits ui, (i=0, 1, 2, . . . , 15), and the encoding is based on a convolutional code, whereby, for each information bit, five associated parity bits pi,k, (k=0, 1, 2, 3, 4) are generated, resulting in 80 codebits. The resulting 80 codebits are punctured to form a (16,77) codeword (c0, c1, c2, . . . , c76). The codebits of the (16,77) codeword are repeated to generate a (16,154) physical layer signaling codeword (c0, c0, c1, c1, c2, c2, . . . , c76, c76) for transmission of the PL data frame over a channel of a communications network.Type: GrantFiled: July 21, 2015Date of Patent: July 12, 2016Assignee: Hughes Network Systems, LLCInventors: Mustafa Eroz, Yezdi Antia, Lin-Nan Lee

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: 20160037456Abstract: An uplink power control system and a machine-implemented method for determining clear sky and adjusting uplink power are provided. A receiving station, which may be a satellite terminal or a satellite gateway, receives a reference signal from a satellite. The reference signal may be sampled over a sampling time period in order to compute a filtered short-term average downlink SINR. A filtered long-term average downlink SINR may be adjusted toward the filtered short-term average downlink SINR using either a first time constant or second time constant, based on a relationship between the filtered long-term average downlink SINR and the filtered short-term average downlink SINR. In some implementations, the second time constant is less than the first time constant.Type: ApplicationFiled: July 30, 2014Publication date: February 4, 2016Applicant: Hughes Network Systems, LLCInventors: Yezdi Antia, Walter Robert Kepley, III

Patent number: 9166675Abstract: Aspects of the invention provide a system and method to allow inroute frame timing synchronization without the aid of hub signal loopback or satellite ephemeris data. Furthermore, it allows tracking and compensating of the satellite motion to allow multiple remotes to use TDMA on the inroute frequencies, while minimizing the aperture. Two main techniques proposed are CLT and polling based approaches, which are used in combination for an optimum solution. In CLT based approach, hub transmits remote specific timing correction feedback messages on the outroute on as needed basis. In polling based approach, the remotes derive their timing based on a per-beam average delay estimate broadcast by the hub and a measured local delay specific to each outroute stream from a remote. An aspect of the invention uses triangulation method to determine satellite position. Furthermore, an aspect of the invention uses hub burst arrival method instead of polling approach.Type: GrantFiled: April 29, 2014Date of Patent: October 20, 2015Assignee: Hughes Network Systems, LLCInventors: Udaya Bhaskar, Yezdi Antia, Satyajit Roy
