摘要： A method and apparatus for determining the location of a node within a communication system is provided herein. During operation, reference nodes (105) having known locations are utilized to locate “blind” nodes (104) whose location is to be determined. More particularly, a blind node (104) wishing to determine its location will measure a plurality of path losses between itself and a plurality of reference nodes (105). These reference nodes' locations will then be mathematically weighted by the path loss between these reference nodes (105) and the blind node (104). The location of the blind node (104) is a sum of the mathematically weighted reference nodes' locations.

摘要： A method and apparatus for determining the location of a node within a communication system is provided herein. During operation, located nodes (105) having known locations are utilized to locate “blind” nodes (200) whose location is to be determined. More particularly, a blind node (200) wishing to determine its location will measure a plurality of signal strengths between itself and a plurality of located nodes (105). Each located node's signal strength will then be adjusted based on at least one antenna gain pattern. A radio-location algorithm will then be executed on the adjusted signal-strength measurements to determine the nodes location.

摘要： A method (500) and system for compensation of frequency offset between a first transceiver (102) and a second transceiver (104) in wireless communication are disclosed. The compensation of the frequency offset between two or more transceivers (102, 104) is achieved using frequency synchronization bursts. These bursts contain information about the frequency offset. The frequency synchronization bursts are transmitted by the first transceiver at a range of frequencies above and below its carrier frequency (502). A second transceiver that receives at least one of these bursts (504) determines the frequency offset (504), and adjusts its frequency to match the frequency of the first transceiver (508). Thereafter, the second transceiver may enter a low power sleep mode (510) in order to reduce its power consumption. The second transceiver returns to active mode (512) just before the start of the transmission of the data packets (514).

摘要： A node (101) using a contention-based access scheme will monitor a channel for a predetermined condition. If the predetermined condition is detected, the node will defect from the contention-based access scheme, where any generated messages will be immediately transmitted. Should a second condition be met, the node will again follow the contention-based access scheme.

摘要： A direct sequence spread spectrum (DSSS) receiver (100) consistent with certain embodiments has a frequency generator (112) that generates a local oscillator signal without use of a piezoelectric crystal. A frequency converter (108) receives the local oscillator signal and mixes the local oscillator signal with a received DSSS signal to produce a down-converted signal. The received DSSS signal is encoded using a first set of DSSS code. A differential chip detector (116) receives the down-converted signal and converts the down-converted signal to a differentially detected signal. A correlator (120) receives the differentially detected signal and correlates the detected signal with a set of DSSS codes that are time-shifted from the first set of DSSS codes. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
