摘要： An adaptive processor implements partial updates when it adjusts weights to optimize adaptation criteria in signal estimation, parameter estimation, or data dimensionality reduction algorithms. The adaptive processor designates some of the weights to be update weights and the other weights to be held weights. Unconstrained updates are performed on the update weights, whereas updates to the set of held weights are performed within a reduced-dimensionality subspace. Updates to the held weights and the update weights employ adapt-path operations for tuning the adaptive processor to process signal data during or after tuning.

摘要： A method and apparatus detects and estimates geo-observables of navigation signals employing civil formats with repeating baseband signal components, i.e., “pilot signals,” including true GNSS signals generated by satellite vehicles (SV's) or ground beacons (pseudolites), and malicious GNSS signals, e.g., spoofers and repeaters. Multi-subband symbol-rate synchronous channelization can exploit the full substantive bandwidth of the GNSS signals with managed complexity in each subband. Spatial/polarization receivers can be provided to remove interference and geolocate non-GNSS jamming sources, as well as targeted GNSS spoofers that emulate GNSS signals. This can provide time-to-first-fix (TTFF) over much smaller time intervals than existing GNSS methods; can operate in the presence of signals with much wider disparity in received power than existing techniques; and can operate in the presence of arbitrary multipath.

摘要： A method and apparatus for reception of signals with unpredictable transmission properties enabling physically secure, unscheduled and interference-resistant communication over machine-to-machine (M2M) networks is claimed. A physical structure comprising combinations of unpredictable physical dwells, spreading vectors, and selection of intended receivers is described. Reception methods employing blind detection and signal separation techniques are then described, which can detect and extract transmissions intended for a receiver, and excise transmissions not intended for that receiver, as part of the despreading procedure, even if received at much higher power levels than the intended transmissions. The resultant receiver eliminates the ability for an adversary to predict and override M2M transmissions; allows reception of ad-hoc transmissions in dense environments without scheduling, CSMA/CA protocols, or feedback paths enabling scheduling, and allows macrodiverse reception of transmissions at networks of connected receivers, thereby providing additional efficiency and security improvements by exploiting the route diversity of the network.

摘要： A receiver processes Global Navigation Satellite System (GNSS) signals transmitted from satellites and non-satellite signals transmitted from beacons. The receiver comprises a symbol-rate synchronous vector channelizer configured to downconvert and channelize a plurality of received navigation signals to produce a vector signal with a sample rate equal to a baseband symbol rate of at least one navigation signal, less any offset due to Analog-to-Digital Converter clock error. A despreader is communicatively coupled to the channelizer and configured to exploit properties of baseband symbol data in the navigation signal to blindly despread the vector signal and extract the plurality of received navigation signals.

摘要： Signals with unpredictable transmission properties enabling physically secure, unscheduled and interference-resistant machine-to-machine (M2M) communication are described. A physical dwell structure containing time slots and frequency channels is established, and a combination of unpredictable physical dwells, spread spectrum modulation with unpredictable spreading vectors, and unpredictable selection of intended receivers is described. These unpredictable transmission properties enable receivers to detect and extract transmissions intended for the receiver, and excise transmissions not intended for the receiver, even if they are received at much higher power levels than the intended transmissions. The system eliminates the ability for an adversary to predict and override M2M transmissions; allows reception of ad-hoc transmissions in dense environments without scheduling, carrier-sense multiple access with collision avoidance (CSMA/CA) protocols, or scheduling feedback paths; and allows macrodiverse reception of transmissions at networks of connected receivers, thereby providing additional efficiency and security improvements exploiting route diversity of the network.

摘要： A method and apparatus for physically secure communication over machine-to-machine (M2M) networks is claimed, through the use of frequency-hop and random access spread spectrum modulation formats employing using truly random spreading codes and time/frequency hopping and receiver selection strategies at the transmitters in the M2M network, blind signal detection and linear signal separation techniques at the receivers in the M2M network, completely eliminating the ability for an adversary to predict and override M2M transmissions. Additional physical security protocols are also introduced that allow the network to easily detect and identify spoofing transmissions on uplinks and downlinks, and to automatically excise those transmissions as part of the despreading procedure, even if those transmissions are received at a much higher power level than the intended transmissions. Extensions to weakly and strongly macrodiverse networks are also described, which provide additional efficiency and security improvements by exploiting the route diversity of the network.
