  • Method and apparatus for preamble synchronization in wireless radio frequency identification (RFID) systems
    Publication number: 20070071036
    Abstract: The present invention provides methods and apparatuses for detection of a preamble portion of a data packet. A plurality of samples are received in an input signal. Samples that occur between consecutive sign changes in the received plurality of samples are counted. The counting of samples is performed a number of times to produce a sequence of counts of samples between consecutive sign changes in the received plurality of samples. Matched filtering of the sequence of counts of samples is performed to determine whether a preamble is detected. Bit rate and timing are initialized for data decoding based on parameters of the sequence of sample counts of a detected preamble.
