Data recovery method and apparatus for radio frequency identification

A data recovery method and an apparatus thereof for RFID(Radio Frequency Identification) are provided to select only a signal validated through signal recovery and integrity processing for I/Q path and reduce a shadow region of a recognition distance through signal processing using a completely recovered signal. An RFID reader(200) for RFID includes a signal receiver(210), a data recovery unit(220), and a signal selector(240). The signal receiver receives a plurality of phase signals. The data recovery unit recovers data for each of the received phase signals. The signal selector selects a signal which satisfies a predetermined condition among the recovered signals.
