Abstract
A radio-frequency identification (RFID) system includes an RFID tag, an RFID reader, and a controller. The RFID reader employs a plurality of phase-offset or phase-diverse channels to improve detection of data transmitted from the RFID tag to the RFID reader. A controller selects the channel that provides the best signal-to-noise ratio and decodes the data provided by the RFID tag using the selected channel.
