  • Method and system for improving time of arrival (TOA) measurements in a wireless communication network
    Patent number: 7653004
    Abstract: A technique for improving the capability of measuring the distance between nodes of a wireless communication network is provided. Technique (800) includes receiving a measured signal, correlating the measured signal with a reference signal to output a measured correlated function, comparing the correlation function to a predetermined reference correlation function, the reference correlation function being based on a predetermined direct path sequence and an estimation of the phase delay of the measured correlated function. A score is assigned to the measured correlation function based on how close the measured correlation function resembles the predetermined reference correlation function. Technique (800) provides improved location accuracy, even in multipath environments, by indicating the quality of the TOA measurement and enabling the selection of a correction mechanism.

    Abstract: An intelligent automatic volume control technique (100) for a communication device is provided that takes a measurement of the background audio environment at the time a user manually selects the volume (102, 104). A user preference is established for the volume setting relative to the background audio level being experienced (106).
