Patent number: 7684425Abstract: A process is described to build physical layer frames with a modcode adapted to the signal quality of a destination terminal. Data packets assigned to the same modcode may be sent in the same frame, although packets associated with higher modcodes may be used to complete a frame before switching to the applicable higher modcode for construction of subsequent frames. After an interval, the order of progression is restarted with an out of order packet above a threshold age. Flow control filtering mechanisms and a variable reliability margin may be used to adapt dynamically to the current data traffic conditions.Type: GrantFiled: October 30, 2006Date of Patent: March 23, 2010Assignee: ViaSat, Inc.Inventor: William H.

Patent number: 7653150Abstract: Architecture for processing a record of burst information in a transmission link. A waveform sampler samples a received waveform containing a record of symbols imposed on a carrier signal. Symbol phase of the record symbols is determined utilizing one or more metrics. Any residual carrier error is corrected, and the carrier signal is removed. The phase and time-of-arrival of the burst information associated with a maximum positive correlation value are then determined.Type: GrantFiled: March 2, 2007Date of Patent: January 26, 2010Assignee: ViaSat, Inc.Inventors: William H.

Patent number: 7634021Abstract: A processor-implemented method of estimating the saturation level of a transmitter from a transmitted communication signal received from the transmitter comprises generating a received data signal from the transmitted communication signal received from the transmitter, generating a transmitted data signal from the received data signal that corresponds to the actual data signal generated at the transmitter, comparing the transmitted data signal to the received data signal, and estimating the saturation level of the transmitter based on the comparison of the transmitted data signal to the received data signal.Type: GrantFiled: November 17, 2008Date of Patent: December 15, 2009Assignee: ViaSat, Inc.Inventor: William H.

Publication number: 20090307727Abstract: Systems, devices, and methods are described for formatting packets for downstream satellite links. The generation of a broadband wireless signal is described, the signal to be transmitted between a gateway and subscriber terminals via satellite. Respective data link layer addresses for the subscriber terminals may each be associated with one or more shortened identifiers for use in lieu of the associated data link layer addresses. This addressing may be included in a stream encapsulation header for an appended data packet. One or more such headers and their appended data packets may then be encapsulated in a baseband frame for transmission within a physical layer frame. Data packets may be fragmented across physical layer frames, and a range of novel formatting techniques may be used to implement the fragmentation.Type: ApplicationFiled: July 16, 2008Publication date: December 10, 2009Applicant: VIASAT, INC.Inventor: William H.

Publication number: 20090279475Abstract: An architecture for the dynamic assignment of links in a multi-user communication system. A plurality of information channels are provided in a forward communication link of the communication system for carrying channel information of the plurality of information channels from a transmitter to a plurality of corresponding receiving devices. The channel information in corresponding select ones of the plurality of information channels is varied dynamically in response to link conditions of the associated receiving devices to more efficiently utilize the channel bandwidth.Type: ApplicationFiled: July 17, 2009Publication date: November 12, 2009Applicant: ViaSat, Inc.Inventors: Mark J.

Publication number: 20090180573Abstract: Methods, systems, and devices are described for estimating a frequency response using a received signal. A first spectral estimation is performed on a digitized representation of an initial version of a wireless signal. A second spectral estimation is performed on the digitized representation of the wireless signal as received from the transmitter. The first spectral estimation is compared with the second spectral estimation to estimate a frequency response. A later signal transmitted from the transmitter may be pre-distorted to compensate for the estimated frequency response. The disclosed frequency response estimation techniques may be used in a satellite communications system.Type: ApplicationFiled: January 10, 2008Publication date: July 16, 2009Applicant: ViaSat, Inc.Inventor: William H.

Publication number: 20090086862Abstract: Cross-polar interference cancellation in a dual-polarization system is described. A terminal in a satellite communication system may receive a first communication signal in a first polarization and a second communication signal in a second polarization substantially orthogonal to the first polarization. The terminal may correlate in-phase or quadrature components of the first communication signal with in-phase or quadrature components of the second communication signal to generate one or more correlation measurements. Correction terms may be generated, using the correlation measurements, to remove at least some of the cross-polar interference.Type: ApplicationFiled: September 30, 2008Publication date: April 2, 2009Applicant: ViaSat, Inc.Inventors: William H.

Publication number: 20090016260Abstract: Systems, methods, and devices are described for scheduling and mapping upstream communications in a satellite communications system. The disclosure includes various channelization and frequency hopping techniques. A gateway is described to perform novel allocation of time slots on upstream frequency channels to allow frequency hopping. A subscriber terminal may perform frequency hopping according to the allocation, and the range may be limited to the transition range of a digitally controlled oscillator unit at the subscriber terminal. A gateway is described to allocate time slots on different upstream frequency channels in a prioritized manner. Subscriber terminals may receive the allocation, and then control the assignment of their upstream traffic to the time slots.Type: ApplicationFiled: July 17, 2008Publication date: January 15, 2009Applicant: ViaSat, Inc.Inventor: William H.
