摘要： A system and method for controlling channel access in a communications system is disclosed. The method and system include providing a data packet to communications queue and determining the priority of the data packet. The method and system also generate a channel occupancy statistic. The channel occupancy statistic is based on the level of activity on a communications channel during a predetermined period. The method and system also compare the channel occupancy statistic to a predetermined threshold. The threshold is based on the priority.

摘要： A method of obtaining coarse synchronization in a frequency hopped/direct sequence spread spectrum (FH/DSS) time division multiple access (TDMA) data link network includes tuning the receiver to a first frequency used in the data link network. Then, signal strength of signals received on the first frequency during a sample time period is observed to obtain a sample energy pattern. An expected energy pattern during a time uncertainty window is determined based upon a known hopping pattern. Then, the sample energy pattern is compared to a first portion of the expected energy pattern, with the first portion of the expected energy pattern corresponding to a first time period within the time uncertainty window. A determination is then made as to whether the first time period is a coarse synchronization candidate based upon the comparison. If it is determined that the time period is a coarse synchronization candidate, one or more additional comparisons on different frequencies can be used to verify the hypothesis.

摘要： A system and method for transmitting a file stream using quality of service capable links. The system has a network capable of supporting quality of service negotiations and an embedded component capable of negotiating different quality of service levels for a plurality of file streams according to importance of bits to be transmitted. To transmit the compressed data, the embedded component identifies important bits and less important bits in the file stream, negotiates quality of service parameters for a plurality of file streams, divides the important bits and less important bits into different file streams having different quality of service levels, and transmits the streams. On the receiving end, the received streams are synchronized and combined into a single stream for the application to display. The error correction and detection coding is performed by physical layers of the network, not the application or embedded component, thereby improving efficiency.

摘要： A method and apparatus for managing communication resources between nodes of a network is disclosed. The network utilizes both dynamic and static assignment of communication time slots. The invention includes a plurality of dynamic nodes wherein communication is accomplished as a result of a node's dynamic assignment to itself of specific time slots from a time multiplex structure. At least one static node is also included in the network. The static node does not participate in the dynamic assignment protocol. Instead, a time slot in said time multiplex structure is pre-assigned for communication with the static node. A dynamic node can serve as a surrogate for a static node, relaying communications between the dynamic and static portions of the network.

摘要： A mobile radio has more than one channel, each channel corresponding to a programmable transceiver circuit. The mobile radio also includes at least one high gain antenna coupled to at least one of the programmable transceiver circuits. A location determining circuit is configured to determine the location of the mobile radio. A processor is coupled to the transceivers and to the location determining circuit. The processor runs a program logic that is configured to identify whether the mobile radio is in a location that enables the mobile radio to extend the reach of the network both due to its location and due to the use of the at least one high gain antenna. The processor also runs a program logic to carry out spectrum sensing to identify available spectral resources based on communication traffic on various frequency bands.

摘要： A follower aircraft is guided to a lead aircraft using a datalink that determines range between the two. The lead aircraft has an antenna array and processing system for determining azimuth/elevation of the follower aircraft. The lead aircraft transmits a ranging message to the follower aircraft and stores a lead aircraft time of transmit (TOT) time. The ranging message is received at the follower aircraft and a follower aircraft time of reception (TOR) time is stored. A second ranging message is transmitted from the follower aircraft to the lead aircraft and a follower aircraft TOT time is stored. The second ranging message is received at the lead aircraft and a lead aircraft TOR is stored. A message is sent from the follower aircraft when follower aircraft TOT and TOR. The range and time offset is determined by the lead aircraft using follower aircraft TOT/TOR and stored lead aircraft TOT/TOR.
