<p>PURPOSE: An RFID tag signals data rate estimation system and a control method thereof are provided to estimate the average of the distances of maximal correlation values through the comparison of a local maximal correlation value location and the latest average correlation value location. CONSTITUTION: A tag signal transmission speed estimation unit(300) calculates the distance between the latest average maximal correlation values by using the maximal correlation values locations in the latest several times. The tag signal transmission speed estimation unit compares the distance between the latest average maximal correlation value locations with the estimated average maximal correlation values based on the local maximal correlation values. The tag signal transmission speed estimating unit estimates the distance between the average maximal correlation locations, and a demodulator(400) demodulates the tag signal based on the estimated average maximal correlation value locations.</p> |
