Abstract: A systematic interferences mitigation design for protected satellite communications (SATCOM) is provided. An advanced channel coding is designed to provide coding gain for SATCOM even in the presence of synchronization errors because of unintentional and intentional radio frequency interferences (RFIs). A unified SATCOM system spectrum efficiency and energy efficiency performance model is developed with a unified interference model for SATCOM dynamic resource allocation (DRA). The SATCOM system DRA is designed with a game theoretic engine and link optimizations providing traffic control, power control, frequency hopping pattern selection, beamforming codebook selection, and modulation with coding agile waveform adaptations. The interferences mitigation design is implemented with software defined radio USRP and GNU-radio to maintain communication link quality of services (QoS).

Abstract: Time-varying input signals are denoised by a neural network. The neural network learns features associated with noise added to reference signals. The neural network recognizes features of noisy time-varying input signals mixed with the noise that at least partially match at least some of the features associated with the noise. The neural network predicts denoised time-varying output signals that correspond to the time-varying input signals based on the recognized features of the noisy time-varying input signals that at least partially match at least some of the features associated with the noise.

Abstract: Systems, apparatuses, and methods for gap-based antenna measurement for antenna switch diversity, where there are fewer number of receivers or transmitters than the number of available antennas. The receivers may switch to additional antennas during a gap and switch back to the previous antennas. A device may select which antennas to use for communications based at least on measurements of additional antennas, thus supporting antenna switch diversity despite having fewer number of receiver chains.

Abstract: A method and system configured to evaluate near range communications quality in an environment. Data describing an environment is obtained from at least one data source (202). The data describing the environment is processed (204) to generate a ground-plane data set (206) describing a ground-plane of the environment, and a 3D object data set (206) describing 3D objects in the environment. These data are used to compute (208) a propagation path between a first location and a second location in the environment, and a near range communications quality characteristic of the propagation path is computed (210).

In response to receiving an indication that that the request has been granted, the one or more processors cause information related to the geographic location to be displayed via the display device, without an express user input at the portable device.

Abstract: This technology relates to a communication apparatus and a communication method adapted to improve the deterioration of communication performance due to variations in parts, for example. A test signal generating section generates a predetermined test signal. A detecting section detects, given a received test signal obtained by a transmitting and receiving section upon receipt of the test signal, an influence parameter affecting the intensity of an active load modulation signal that combines a transmission carrier with a synchronizing signal synchronized with a received signal obtained upon receipt of the transmission carrier. A controlling section controls the intensity of the active load modulation signal in accordance with the influence parameter. This technology applies to cases where short-range wireless communication is performed using magnetic fields.

Abstract: For determining operational status of components of a wireless signal transmission environment, a signal is received from a client power receiver (CPR), and at least one waveform characteristic value of the signal is calculated. Based on the determined waveform characteristic value(s), a current transceiver system operational status is computed for the CPR at a current location. The determined current transceiver system operational status is compared with a prior-stored last known good transceiver system operational status for the CPR at the current location, and it is determined if, as a result of the comparing, the current transceiver system operational status matches the prior-stored last known good transceiver system operational status for the CPR at the current location. Determining a presence or an absence of the match facilitates identifying one of a presence and an absence of: functional problem(s) in: at least one of the transceiver system and the CPR.
