Patent number: 9036661Abstract: Systems, devices, processors, and methods are described which may be used for the reception of a wireless broadband signal at a user terminal from a gateway via a satellite. A wireless signal may include a series of physical layer frames, each frame including a physical layer header and payload. The received signal is digitized and processed using various novel physical layer headers and related techniques to synchronize the physical layer frames and recover data from physical layer headers for purposes of demodulation and decoding.Type: GrantFiled: February 12, 2013Date of Patent: May 19, 2015Assignee: ViaSat, Inc.Inventors: Donald W. Becker, Matthew D. Nimon, William H. Thesling

Patent number: 8897409Abstract: Symbol timing acquisition is described for a wireless broadband signal received at a user terminal from a gateway via a satellite. In-phase and quadrature channels of the wireless signal may each be sampled at a rate of one sample per symbol. The samples may be interpolated to generate an early interpolation and a late interpolation for each of the samples. A difference measurement is obtained between the early interpolation and the late interpolation for a set of the samples. A number of the difference measurements may be averaged, and symbol timing may be modified based on the average. This process may be continued on an iterative basis to acquire symbol timing.Type: GrantFiled: April 19, 2012Date of Patent: November 25, 2014Assignee: ViaSat, Inc.Inventors: Donald W. Becker, Matthew D. Nimon, William H. Thesling

Patent number: 8683283Abstract: Systems, devices, processors, and methods are described which may be used for the reception of a wireless broadband signal at a user terminal from a gateway via satellite. A physical layer header may be identified, the header including a number of subcode blocks. A phase may be estimated for each of the subcode blocks, and intra-header phase differences may be calculated. The intra-header phase differences may be used to calculate a frequency error, which may be corrected. Frequency errors may be monitored and, when such errors fall below a threshold level, an alternative inter-frame frequency error tracking method may be used.Type: GrantFiled: December 18, 2009Date of Patent: March 25, 2014Assignee: ViaSat, Inc.Inventors: Donald W.

Patent number: 8170158Abstract: 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: GrantFiled: September 30, 2008Date of Patent: May 1, 2012Assignee: ViaSat, Inc.Inventors: William H. Thesling, Richard T. Gedney, Matthew D. Nimon, Fan Mo

Patent number: 7961666Abstract: 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: GrantFiled: March 8, 2010Date of Patent: June 14, 2011Assignee: ViaSat, Inc.Inventors: Mark J.
