Abstract: A method and apparatus for providing a standalone anti-jamming (AJ) nuller-beamformer. Signals from an antenna array include a sum of Global Navigation Satellite System (GNSS) signals and jamming signals from a plurality of spatial sources. A front end is configured to amplify, filter, down-convert, and sample the input signals which are then filtered, downconverted, and decimated prior to frequency-domain and time-domain partitioning. Weights are computed and applied for spatial nulling of jamming signals in each frequency bin for the partitioned signals. Frequency and time-domain reconstruction generates a reconstructed signal with suppressed jamming.

Abstract: A non-volatile computer data storage programming system includes a scan chain modification configured to receive a default model defining a scan chain of an industry standardized device. A controller is in signal communication with the scan chain modification system, and is configured to program an industry standardized device. A non-volatile computer data storage device is configured to receive data from the industry standardized device. The scan chain modification system modifies the default model to generate a new model including a reduced scan chain, and the controller programs the industry standardized device based on the new model such that the industry standardized device is programmed with the reduced scan chain.

Abstract: A technology is provided for reducing pulsed radio frequency interference. The GPS signal may be received at a GPS device. The GPS device may include a GPS receiver. The GPS signal may include a plurality of sign and magnitude bits. Pulsed RFI may be detected in the GPS signal based on samples of the magnitude bits in the GPS signal. The pulsed RFI received at the GPS receiver may be reduced by communicating a blank signal when the samples of the magnitude bits indicate the pulsed RFI.
