PASSIVE RFID READER, PASSIVE RFID TAG, AND METHOD FOR TRANSMITTING/RECEIVING USING EXTENDED PIE ENCODING/DECODING THEREOF

摘要

The present invention relates to a modulation method of pulse-interval encoding (PIE) of a radio frequency identification (RFID) system. The modulation method of pulse-interval encoding (PIE) of a radio frequency identification (RFID) system for modulating 2-bit send data includes: a step of controlling the length of the symbol according to the value of the first bit of the send data; and a step of controlling the length of energy transmission waiting section according to the value of the second bit of the send data.
