摘要： An architecture for a frequency hopped spread-spectrum transmitter-receiver in an advanced tactical data link packet switched network that ensures optimal Statistical Priority-based Media Access (SPMA) performance, enables more efficient packing of hop channels in a given allocated bandwidth and counteracts hostile jamming. The transmitter-receiver supports a scalable symbol rate mode that reduces the symbol rate in the time domain and decreases the bandwidth in the frequency domain, over a predetermined prior value. A transceiver according to the present architecture is able to statically or dynamically scale the symbol rate of transmissions, operate in burst mode and change the hop set. In one embodiment the transceiver is part of a Software Defined Radio (SDR).

摘要： An apparatus and method for providing external bump-in-the-wire cryptographic capability to a legacy radio (which may or may not include embedded cryptography) includes an appliqué couplable to the legacy radio and to an intercom, handset, or other user device. The appliqué extracts and stores in memory radio status information from the legacy radio (channel information, cryptographic instructions, alarm conditions) by intercepting control signals, polling the legacy radio, or listening in on channels used by the legacy radio. If TSVCIS 2.1 or CMI-compatible encryption is required, the appliqué may encrypt or decrypt a message with the appropriate cryptographic keys based on the extracted radio status information. The appliqué may include a bump-in-the-wire device or a bump-in-the-connector device directly couplable to an intercom port of a vehicular mounted SINCGARS legacy radio.

摘要： A method for determining an angle-of-arrival for a detected signal. The method includes the steps of receiving the signal at a first antenna, receiving the signal at a second antenna, generating a plurality of spectral lines based on a complex multiplication of a complex conjugation of the signal received at the first antenna and the signal received at the second antenna, generating a delta phase difference for pairs of the spectral lines using frequency differences, and generating an angle-of-arrival for the detected signal based on an average of the delta phase difference.

摘要： An interference cancellation system supports a dynamic operating range from maximum interfering signal level to the on-channel noise floor. The system uses a novel combination of analog and digital processing effectively cancelling 1) high-level interfering signal components, 2) low-level interfering noise, and 3) distortion components. The system employs an interrelated combination of cross-domain analog and digital processing techniques to defeat the inherent dynamic range limitations existing in either individual domain.

摘要： An extended length strand take up device is presented that may be used to repair damaged guy wires in the field. The invention comprises two connecting bodies connected by a single tension rod that extends continuously between the two connecting bodies. Each connecting body slides over opposite ends of the tension rod and is held in place by a stop member, such as threaded nuts screwed onto the respective ends of the tension rod. The connecting bodies may further include an inwardly-facing pull tab or tabs that can be used for pre-tensioning the guy wire. An alternative embodiment of the invention comprises a single tension rod that is fixedly anchored to the ground and several connecting bodies that are fixedly mounted along the end of the guy wire at standard increments. The tension rod runs parallel to and overlaps the end of the guy wire. The connecting bodies slide along the length of the tension rod until the required tension and length is reached. A stop member, such as a threaded nut, is screwed onto the end of the tension rod holding the connecting bodies in place.

摘要： A type of channel access, Clique Activated Multiple Access (CAMA), is disclosed which allows neighboring nodes to form cliques for the purpose of supporting a broadcast channel. CAMA operates using only local knowledge, meaning it can scale to large networks. It also has the potential of requiring less channel resources than node allocation. In addition, it would lend itself well to an application like push-to-talk voice where only one transmitter per neighborhood is active (except for relay nodes.

摘要： The present invention is a wireless communication system and method. In an exemplary embodiment, the system includes a plurality of transceiver nodes arranged in a network and configured to communicate between transceiver nodes using an Orthogonal Domain Multiple Access (ODMA) frame structure, each of the plurality of transceiver nodes having neighboring nodes. Each ODMA structure may include a plurality of bootstrap slots for each of the plurality of transceiver nodes. Further, a plurality of correlation sequences may be defined within each of the plurality of bootstrap slots in which each correlation sequence included within the plurality of correlation sequences is located in a separate antenna sector and sub-sector. Addition of the plurality of correlation sequences to each of the plurality of bootstrap slots allows for recursive directional determination of which antenna sector and sub-sector is to be used to communicate with one of the plurality of transceiver nodes.
