Abstract:
An apparatus and a method for demodulating a subcarrier tag signal in a radio frequency identification (RFID) reader is provided. The apparatus for demodulating the subcarrier tag signal in the RFID reader may include: an edge signal generation unit receiving a subcarrier tag signal and generating an edge signal with respect to the tag signal; an edge information extraction unit extracting edge information from the generated edge signal; and a decoding unit decoding the tag signal using the extracted edge information.
