Patent Images
1. A transmitting method using extended Pulse-Interval Encoding (PIE) in a Radio Frequency IDentification (RFID) system, comprising:
- configuring a transmitted frame including data to be transmitted to an RFID tag; and
encoding the data in the transmitted frame by two bits in one symbol section,wherein the encoding comprises;
adjusting a length of a symbol according to a value of a first bit of 2-bit data to be encoded in each symbol section; and
adjusting a length of an energy transfer waiting section according to a value of a second bit of 2-bit data to be encoded in each symbol section.
