Publication number: 20150341109Abstract: A communication system includes a satellite and a ground station. The satellite is configured to preferentially receive signals from each of a plurality of sub-regions within a region of communication of the satellite. The ground station is configured to determine a location of the ground station, determine in which of the sub-regions that the ground station resides based on the location, and transmit a signal to the satellite during a time-interval assigned to the sub-region. The ground stations time-multiplex the transmission of signals from various ground stations to the satellite based on which sub-region of the larger region (e.g. the continental United States or CONUS) that the ground station resides. The time multiplexing is such that ground stations in one region are not transmitting signals to the satellite during the same time interval as ground stations in adjacent sub-regions.Type: ApplicationFiled: May 20, 2014Publication date: November 26, 2015Applicant: DELPHI TECHNOLOGIES, INC.Inventor: ERIC A.

Satellite communication having distinct low priority information broadcast into adjacent sub-regions
Patent number: 9042809Abstract: A satellite communication system using hierarchical modulation to transmit a plurality of modulated signals to sub-regions within a region. Each modulated signal includes high priority content and low priority content. The system includes a satellite equipped with a plurality of satellite transmitters coupled to a plurality of antenna elements, e.g. a phased array of antenna elements. The antenna elements are utilized selectively to direct a modulated signal from a satellite transmitter to a distinct sub-region. The satellite transmitters and antenna also cooperate to broadcast the high-priority content to the region such that a ground receiver traveling from a first sub-region to an adjacent second sub-region adjacent will not experience a loss of high-priority content. First low-priority content of a first modulated signal directed to the first sub-region is independent of second low-priority content of a second modulated signal directed to the second sub-region.Type: GrantFiled: March 19, 2013Date of Patent: May 26, 2015Assignee: Delphi Technologies, Inc.Inventors: Glenn A.

Patent number: 7903629Abstract: High priority data and low priority digital data are transmitted as primary and secondary data in hierarchically modulated, orthogonal frequency division multiplexing (OFDM) from an earth-orbiting satellite. To enable the transmitter amplifier to be operated with less back-off from saturation without clipping, the low priority OFDM symbols have fewer samples than the high priority OFDM symbols, and the high priority samples on which the low priority samples are superimposed are selected according to a first deterministic rule using sample power comparisons of the high priority samples to concentrate the low priority samples on those high priority samples having lower (optimally, the lowest) sample power. The low priority samples are distributed on the selected high priority samples according to a second deterministic rule relating the original low priority sample order to the original high priority sample order.Type: GrantFiled: January 30, 2009Date of Patent: March 8, 2011Assignee: Delphi Technologies, Inc.Inventors: Glenn A.

Patent number: 7830983Abstract: The present invention provides a method to minimize degradation in a D-MPSK hierarchical modulation system by adding additional data throughput (i.e., secondary information) as an offset to the primary signal transmitted by a SDARS terrestrial repeater.

Patent number: 7822149Abstract: Additional data may be added to the current SDARS satellite signals as a phase and/or amplitude offset from the legacy quadrature phase shift keying (QPSK) modulated data and transmitted by the SDAR terrestrial repeaters. However, in the case where a legacy receiver architecture for a differential modulation system outputs angular/phase differences between carriers, the phase and/or amplitude information appears as distortion to the legacy receiver. The present invention provides a method for optimizing the SDARS infrastructure more efficiently by allowing independent adjustment of the phase and/or amplitude offset (610) at each terrestrial site. The present invention provides a method for adjusting the performance of each signal together or separately as needed.Type: GrantFiled: June 2, 2005Date of Patent: October 26, 2010Assignee: Delphi Technologies, Inc.Inventors: Eric A.

Patent number: 7773697Abstract: Where the additional data throughput is added using an amplitude offset or a combination of phase and amplitude offset, the legacy differential demodulator does not recover the amplitude information. The present invention provides a method for demodulating amplitude offsets in a differential modulation system in order to recover the amplitude information. The demodulated amplitude information may be used to recover the additional Level 2 data transmitted as an amplitude offset or combination phase and amplitude offset in a differential multiple phase shift keying (D-MPSK) transmission, such as across adjacent OFDM symbols and/or adjacent frequency subcarriers.Type: GrantFiled: March 23, 2005Date of Patent: August 10, 2010Assignee: Delphi Technologies, Inc.Inventors: Eric A.
