摘要： A secure wireless transceiver, such as a link 16 transceiver, receives signals using an antenna array having an SOC associated with each antenna element in the array. The SOC's digitize and channelize received data for transmission to a message nulling system that mitigates jamming. The antenna array can be conformal, and can replace an existing Link 16 blade. The disclosed transceiver can be a modified CMN-4 transceiver with digitizing and channelizing moved to the SoC's, and replaced by the nulling system. The transceiver uses applicable TRANSEC information to assign received data to the logical Link 16 channels before nulling, and embodiments apply nulling only to channels of interest, thereby improving the nulling and reducing side lobes. Embodiments distinguish between desired and unwanted signals based on known Link 16 signal features and/or situational awareness, rather than signal amplitudes, thereby enabling nulling of even weak jamming signals.

摘要： A process for allowing a CMN-4 equipped Link 16 terminal to enter an active network. After an initial entry command is entered at the terminal at a given current time at the terminal, a number of time slots are identified in which multiple receivers at the terminal have an opportunity to detect an initial entry message (lEM) after the given current time. Each of the receivers is set to detect an lEM during a different one of the identified time slots. When an lEM is first detected by one of the receivers, the current time at the terminal is reset based on the time slot in which the I EM was detected.

摘要： A method for mitigating the effect of a localized jamming attack on a secure, tactical wireless network implements a dynamic relay assignment ("DRA") approach, whereby nodes are dynamically assigned to relay communications to "disadvantaged" nodes that are subject to the attack, the relay nodes being selected based on their communication reliability and their proximity to the disadvantaged nodes. In embodiments, the nodes share with each other performance statistics and, in embodiments, measured local noise levels. In various embodiments, each node provides data to a "strategy optimizer" which then dynamically makes relay assignments. In Link- 16 embodiments support for a "DRA" relay mode is added, and the communication protocol is extended to support the required exchange of communication quality and local noise information via PPLI messages.

摘要： A method for implementing interference mitigation in wireless network such as a Link (16) network does not require interference recognition and does not degrade signal detection even in the absence of interference. An unmitigated correlation score is obtained by correlating received, unmitigated preamble symbols with expected symbols. At least one of the input signals is also correlated after mitigation to obtain a mitigated signal. A mitigated correlation sore is obtained from the mitigated signals, and a mixed correlation score is obtained by combining mitigated and unmitigated signals. A signal is detected if any of the correlation scores exceeds a corresponding threshold. Embodiments use the unmitigated correlation for subsequent message time of arrival determination if the unmitigated correlation score is above its detection threshold. In embodiments, mitigation is applied to only one of the message frequencies. Implementation of the disclosed method does not require excessive additional electronic resources.

摘要： An auto-ICAS compliant system and method of avoiding collisions between aircraft linked by a Link 16 network comprises establishing an ICAS datalink between aircraft less than 10 nautical miles apart. Datalink messages generated and processed by ICAS datalink modules are transmitted and received by Link 16 receivers rather than dedicated ICAS transceivers. The datalink messages are embedded within the propagation delay portions of Link 16 timeslots and exchanged among up to 10 nearby aircraft at a data rate of up to 20 Hz each. Because each Link 16 timeslot can contain a Link 16 message and two 768-bit ICAS datalink messages, conventional Link 16 communication is not impeded. Datalink messages can be software encrypted. Link 16 messages can be encoded using an enhanced throughput Link 16 protocol that includes fewer preamble pulses and/or eliminates STN information. Embedded datalink messages can be transmitted at 1 Watt by a MIDS-JTRS CMN4.

摘要： A method for reducing self-interference in a wireless network, such as a Link 16 network, while maintaining simultaneous multiple access takes advantage of the physical proximity of nodes in a localized subnetwork, such as a fighter-to-fighter subnetwork in a flight wing, by actively reducing the transmit powers used for subnet messages between the nodes. Calibration messages such as Precise Participant Location and Identification (PPLI) messages are exchanged between all of the nodes of the localized subnetwork, from which each node determines the identities, transmit powers, noise levels, and SNRs of all of the other nodes. The node then determines a link margin for other nodes, and sets its transmit power to a "safe" level for the subnetwork according to the lowest link margin.
