  • Patent number: 10356843
    Abstract: Embodiments are directed to systems and methods for selecting appropriate transmission configurations in a mobile ad hoc frequency division duplexing mesh network. In one scenario, a node receives transmission parameters from a neighboring node, where the transmission parameters include an indication of the node's current transmission configuration. The node receives network parameters from neighboring nodes, where the network parameters include connection information describing the node's current network connection to the neighboring nodes. Then, based on the received transmission parameters and the received network parameters, the node calculates a change factor which indicates the desirability of changing transmission configuration.

  • Patent number: 10186059
    Abstract: Embodiments are directed to representing radio frequency (RF) signals in a visualization using particle bursts. In one scenario, a computer system instantiates RF signal sources in a virtualization, where each RF signal source is configured to emit RF signals. The computer system then generates a stream of particle bursts to represent at least one of the emitted RF signals, and provides a visualization that shows the instantiated RF signal sources along with the generated particle bursts representing the emitted RF signals. In some cases, the visualization may be used to illustrate an anti-access, aerial denial (A2AD) environment. In other cases, the visualization may be used to illustrate network communications using particles, where each particle represents network data packets.

  • Patent number: 10181972
    Abstract: Embodiments are directed to systems and methods for communicating between nodes in a mobile ad hoc network. In one scenario, a node in a mobile ad hoc network communicates with another node in the network using both code division multiple access (CDMA) and frequency division duplexing. The communication is coded prior to transmission to the other node, and includes applying direct sequence spread spectrum (DSSS) modulation to a transmission signal at a specified bit rate over a specified spectrum. The DSSS coding is applied in accordance with a processing gain which spreads the spectrum relative to the bit rate of the transmission. The coded communication is then transmitted over a specified frequency band allocated to the node over which the node transmits data and over which the other node receives the data.

  • Patent number: 10140772
    Abstract: Embodiments are directed to visualizing electromagnetic (EM) particle emissions in a computer-generated virtual environment. In one scenario, a computer system accesses portions of data representing EM particle emissions emitted by a virtualized EM particle emitter. The computer system generates a particle visualization that includes at least a portion of the EM particle emissions being emitted from the virtualized EM particle emitter within the virtual environment. The particle visualization includes an indication of the EM particle emissions' interactions with other virtual or non-virtual elements in the virtual environment. The computer system then presents the generated particle visualization in the computer-generated virtual environment. In some cases, the computer system further receives user input intended to interact with virtual elements within the virtual environment.

  • Patent number: 9983247
    Abstract: The presence of a hidden signal can be detected efficiently using frequency domain multiplication. A detector system can be employed to search for a hidden signal across a wide spectrum in real time. The detector system can divide multiple antenna inputs into a series of blocks and then convert these blocks to the frequency domain possibly in a parallel fashion. Corresponding blocks from each input can then be conjugate multiplied, and the results of this conjugate multiplication can then be averaged over time. If a signal is hidden in the inputs, this averaging will reduce the noise floor thereby revealing the presence of the hidden signal at a particular frequency.

  • Patent number: 9214915
    Abstract: The estimated gain profile of an amplifier can be modified during operation of the amplifier utilizing detected values of the amplification level of signals produced by the amplifier. The amplification levels can be detected at a location that is remote from the amplifier. New expected amplification levels can be determined for corresponding control signal values in the estimated gain profile. Digital filtering such as Kalman filtering can be used to determine the new expected amplification levels. The estimated gain profile can be modified with the new expected amplification levels.

  • Patent number: 9191252
    Abstract: A system in which a sending node sends modulated waveform signals to a receiving mode can include the capability to change the waveform type of the modulated waveforms from a current waveform type to a new waveform type. The sending node can generate and send to the receiving node a variable length header that provides the receiving node sufficient information for the receiving node to demodulate modulated waveform signals modulated in accordance with the new waveform type. The variable length header can identify the parameters in a parameter set defining the new waveform type that have different values as compared to the current waveform type.

  • Patent number: 9130689
    Abstract: The present invention is generally directed to using code division multiplexing (CDM) on the beacon and traffic channels while lowering the power of the beacon channel so that it rides under the traffic channel and becomes very difficult to detect. In this way, the beacon channel can contain sensitive information for decoding the traffic channel while remaining hidden from unintended recipients. By hiding the beacon channel, the CDM technique can be particularly beneficial in adaptive waveform systems where sensitive traffic channel acquisition information is regularly transmitted to the receiver.

  • Patent number: 8954832
    Abstract: A digital electronic message comprising datawords to be transmitted in a communications system can be encoded prior to transmission using an asymmetric error detection coding scheme. The coding scheme is asymmetric because the coding scheme includes multiple codeword groups each with a different minimum coding distance. The codewords in a group having a greater minimum coding distance can correspond to datawords that have a relatively high susceptibility to transmission errors. The codewords in a group having a lesser minimum coding distance can correspond to datawords that have a relatively low susceptibility to transmission errors.

  • Patent number: 8509711
    Abstract: Wireless terminals, systems, and methods use interlaced diplexers. A first diplexer can provide a first pair of bands separated by a first separation band, and a second diplexer can provide a second pair of bands separated by a second separation band. The first separation band and the second separation band can overlap. Transceivers (comprising transmitters and receivers) can be coupled to the diplexers to provide frequency-division duplex communications using one or both of the pairs of bands.
