    摘要: Apparatus and method for improving the detection of signals obscured by noise using stochastic resonance noise. The method determines the stochastic resonance noise probability density function in non-linear processing applications that is added to the observed data for optimal detection with no increase in probability of false alarm. The present invention has radar, sonar, signal processing (audio, image and video), communications, geophysical, environmental, and biomedical applications.

    摘要: During operation, nodes that receive beacons from a different network will synchronize to the different network when a predetermined condition is met. Synchronization to the differing network will only take place if the node receiving the beacon from a different network does not have access to a fixed network coordinator and the predetermined condition is met. The predetermined condition may comprise such things as a Network ID for the different network being larger than the Network ID for the current network, or alternatively, the size of the different network being larger than a size of the current network.

    摘要: A method and apparatus for synchronizing a node (200) within an ad-hoc communication system (100) is described herein. During operation all nodes periodically broadcast a synchronization beacon for other nodes to utilize for synchronization when a coordinating access point (node) is unavailable. A particular node's synchronization beacon will have an associated “tier” number that is incremented from the tier number of the beacon used to synchronize the particular node. In the absence of an access point, a node that joins the ad-hoc communication system will listen for synchronization beacons transmitted by other nodes. If synchronization beacons are heard, the node will synchronize with a beacon having a lowest tier. The node will then broadcast its own beacon having its tier number incremented from the lowest tier beacon heard.
