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.
