Patent number: 11309955Abstract: Systems and methods are described herein for communications bandwidth enhancement using Orthogonal Spatial Division Multiplexing (OSDM). For example, large sparse antenna arrays may be able to distinguish between signals emitted by multiple nearly collocated antennas, even if the signals have the same frequency, polarization, and coverage. Thus, the use of a large sparse antenna array may be able to resolve/isolate individual antennas on a single platform, allowing for OSDM, analogous to Orthogonal Frequency Divisional Multiplexing (OFDM). Using OSDM, multiple antennas on the same vehicle are able to reuse the same frequencies/polarizations without interference, thereby increasing spectrum availability while still providing the same transmitter power spectral density and total RF power emission.Type: GrantFiled: February 10, 2020Date of Patent: April 19, 2022Assignee: Northrop Grumman Systems CorporationInventor: Leonard A. Atkinson

Patent number: 10998963Abstract: Methods and systems are provided for a protected communications architecture in which a pool of limited availability channels are shared through the transmission of encoded symbols with time-varying path diversity by a pool of users. The communications architecture can be managed by a network controller that stores availability data describing the availability of multiple-access satellite communications channels. The network controller allocates a first user to a first time-varying subset of the plurality of multiple-access satellite or terrestrial communications channels based on the availability data. The network controller updates the availability data based on the allocation of the first user. The network controller allocates a second user to a second time-varying subset of the plurality of multiple-access satellite or terrestrial communications channels based on the updated availability data.Type: GrantFiled: August 30, 2019Date of Patent: May 4, 2021Assignee: Northrop Grumman Systems CorporationInventor: Leonard Atkinson

Publication number: 20050013385Abstract: A carrier suppressed information signal modulation arrangement employs a plurality of serially coupled carrier suppression modulators. Each of the serially coupled modulators has a carrier input, a modulating signal input and a modulated carrier output. A carrier is applied to the carrier input of the first modulator and the suppressed modulated carrier output of each modulator is coupled to the carrier input of the succeeding modulator. An encoder generates modulating signals to be applied to the modulating signal inputs of the serially coupled modulators in response to the information signal. The modulating signals applied to each of the serially coupled modulators modifies the modulated carrier output received at its carrier input to produce a suppressed modulated carrier at the output of the last of the serially coupled modulators that corresponds to the information signal.Type: ApplicationFiled: June 1, 2004Publication date: January 20, 2005Applicant: Orbital Sciences Corp.Inventor: Leonard Atkinson
