Patent number: 7724698Abstract: A satellite communications system adjusts a modulation and coding format for a downlink based on the slant range distance from the satellite to the receiving ground terminal. Modulation and coding formats are each associated with different sets of slant range distances. An estimated slant range from a satellite to a receiving ground terminal for a time period is determined, and the modulation and coding format associated with that slant range distance is identified. Data may then be transmitted by the satellite to the receiving ground terminal using the identified modulation and coding format for the time period. Additional factors may be considered in identifying the applicable modulation and coding format to be used.Type: GrantFiled: January 8, 2008Date of Patent: May 25, 2010Assignee: ViaSat, Inc.Inventors: Rodney A. Morris, John R. Zlogar, Mark J. Vanderaar

Publication number: 20090016718Abstract: Systems, methods, and software are described for wirelessly distributing data from a Passive Optical Network (PON). The system includes a PON for transmitting an optical signal. The system further includes a distribution terminal coupled with the PON. The distribution terminal is to receive the optical signal, convert the optical signal to a set of data, and transmit the set of data via a wireless signal. The system further includes a first customer endpoint in communication with the distribution terminal. The first customer endpoint is to receive the wireless signal, demodulate and process a first subset of the set of data from the wireless signal, and then forward a second subset of the set of data via a second wireless signal. The system includes additional customer endpoints in communication with the first customer endpoint. The additional customer endpoints are configured to receive the second wireless signal and process the second subset.Type: ApplicationFiled: July 10, 2008Publication date: January 15, 2009Applicant: ViaSat, Inc.Inventors: Michael Lorre Lubin, Mark J.

Patent number: 5910967Abstract: A communication system (11) uses concatenated coding in which an inner code is configured to match the needs of an outer code. The inner code is implemented through a pragmatic trellis coded modulation encoder (18) and decoder (34). A parser (50) of the encoder (18) distributes fewer than one user information bit per unit interval (66) to a convolutional encoder (58) which generates at least two convolutionally encoded bits for each user information bit it processes. Exactly one of the convolutionally encoded bits is phase mapped (56) with at least two user information bits during each unit interval (66). The decoder (34) detects a frame sync pattern (48) inserted into the user information bits to resolve phase ambiguities. Phase estimates are convolutionally decoded (100) to provide decoded data estimates that are then used to selectively rotate the phase estimates prior to routing the phase estimates to a slice detector (118).Type: GrantFiled: October 20, 1997Date of Patent: June 8, 1999Assignee: Sicom, Inc.Inventor: Mark J.

Patent number: 5657354Abstract: The optimum decoding of component codes in Block Coded Modulation (BCM) schemes requires the use of the Log-Likelihood Ratio (LLR) as the signal metric. The essence of the invention is a means of accurately approximating the computation of the LLR in a way which is simple to implement directly. The invention, the Log-Likelihood Ratio Planar Approximation (LLRPA), mathematically consists solely of planar equations with fixed point arithmetic that provides both an accurate estimate of the LLR and is easily realized in electronic hardware.Type: GrantFiled: May 15, 1995Date of Patent: August 12, 1997Inventors: William H.
