The present disclosure relates generally to a network system having multiple users, multiple inputs, and multiple outputs to transmit data from a data source through a link to a data sink. One example of a Multi-user multiple input multiple output (MU-MIMO) system relates to the use of primary transceivers and secondary transceivers in respective networks that effectuate data transmission. The primary transceivers are coupled with a data source and broadcast or transmit the data source signal to a plurality of secondary transceivers in a local area network. The signal is then transmitted over a long link to another set of secondary transceivers that then pass the signal to another primary transceiver. This another primary transceiver is coupled with the data sink to effectuate signal transmission to the data sink. The data is synchronized in manner that requires minimal processing and does not require closed loop phase control.

Techniques are provided for automatic gain control processing to reduce adverse effects associated with clipped samples resulting from conversion of analog signals to digital signals. A methodology according to an embodiment includes identifying a clipped sample of the digital signal, for example by comparison of the digitized sample values to a threshold value associated with a full scale value of the converter. The method also includes applying a window function to portions of the digital signal. The window function is configured to attenuate samples of the digital signal within a region centered on the identified clipped sample. A Hilbert finite impulse response (FIR) filter may be applied to the digital signal prior to applying the window function. Parameters of the window function are selected based on frequency response characteristics of the FIR filter and on signal to noise ratio requirements of an application that receives the windowed digital signal.

LINK 16 DATALINK FOR INTEGRATED COLLISION AVOIDANCE SYSTEM

Chongoushian, John H.
Lang, James W.
Abrégé
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.

A sensor determines the spin rate or rotation frequency of a munition body of a guided projectile relative to precision guidance munition assembly. The spin rate is used to determine launch velocity of the guided projectile early in flight before GPS is operationally active. The launch velocity is used to determine whether a corrective maneuver is needed to change the range of the guided projectile. Logic can control the canards on the canard assembly in response to the determination that a corrective maneuver is needed.

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.

ENHANCED LINK 16 DETECTION WITH INTERFERENCE MITIGATION

Inventeur(s)
Lang, James W.
Berry, Michael J.
Chongoushian, John H.
Abrégé
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.
