摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus of detecting a response end point of a radio frequency identification tag which can detect an end of signal (EOS) of a received response signal in order to transmit a subsequent signal within a predetermined time, when receiving the response signal from an RFID tag after transmitting a command signal from a reader of a radio frequency identification system to the RFID tag.
SOLUTION: The method of detecting the end of signal for the radio frequency identification tag includes a step of obtaining a threshold based on a continuous signal in a section having no response signal; a step of measuring a variance value in a sliding window while moving the sliding window for the response signal; a step of comparing the variance value with the threshold and counting the number of times when the variance value is smaller than the threshold; and a step of determining that a time when the number of counts is not less than the predetermined times is the end of the response signal.
