  • Patent number: 8982928
    Abstract: A method for detecting multi-user signals including conducting a first energy burst detection detecting a first plurality of user signals as a first energy burst, attempting to decode a user signal from the first plurality of signals within the first energy burst, cancelling out a first user signal from the first energy burst if the first user signal is successfully decoded from the first energy burst, determining a second user signal to be discarded if the second user signal is not successfully decoded from the first energy burst, conducting a second energy burst detection detecting a second plurality of signals as a second burst, and iteratively cancelling out the first user signal successfully decoded from the first energy burst from the second energy burst, wherein the second energy burst detection is conducted when all user signals within the first energy burst are either cancelled out or determined to be discarded.

  • Patent number: 8064551
    Abstract: Described are computer-based methods and apparatuses, including computer program products, for determining burst transmission signals. A receiver receives radio frequency data from a data source through a network. The receiver converts the radio frequency data to digital data. The receiver converts the digital data to baseband data. The receiver generates a correlation magnitude from the baseband data based on one or more correlation templates. The receiver determines one or more statistics based on the correlation magnitude and stored statistics. The receiver determines the presence of a burst transmission signal based on a comparison of a threshold value computed as a function of the statistics and the correlation magnitude. If the correlation magnitude exceeds the computed threshold, the receiver demodulates the burst transmission signal to packet data and transmits the packet data to a server.
