摘要： A block-code-based structure that allows cross-packet coding of data using a sliding window. In this structure, each transmitted packet contains both information symbols and parity symbols generated by the information in previous packets. This code structure allows a receiver to recover lost packets without additional transmissions. If enough packets have been lost so that the receiver cannot recover one or more of them, new parity symbols can be generated and transmitted as additional packets. The parity symbols in these additional packets may be used by multiple receivers. Thus, the sliding window block code reduces retransmission overhead, particularly for multicast applications. Furthermore, the sliding window structure does not produce an encoding delay between the arrival of data and its transmission and reduces the decoding delay between the loss of a packet and its recovery.

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.

摘要： A method of utilizing communication channel resources between nodes in a network of nodes is provided. Communication between a set of nodes in a communication network uses a time division multiple access protocol that includes a plurality of time slots. A set of time slots is allocated from the plurality of time slots to a first node of the set of nodes for transmission of a communication signal. At the first node, a time slot of the allocated set of time slots is identified that is no longer needed for transmission of the communication signal. Instead, the first node tunes to a network synchronization frequency during the identified time slot and receives a synchronization signal transmitted by a second node. The second node is not one of the set of nodes in the communication network. The first node synchronizes with the second node using the synchronization signal thereby allowing communication between the second node and the set of nodes.

摘要： A method of communicating over a network of nodes is disclosed. According to the method, it is determined whether a first node forms part of an interconnected sub-network within the network. Broadcast slots are assigned to the first node if the first node is part of the sub-network. The first node is permitted to use the assigned broadcast slots to broadcast data to other nodes. Nodes within one hop of the first node but not forming part of the sub-network are permitted to use an assigned broadcast slot if the first node is not using the broadcast slot.
