Abstract
Provided are an RFID reader and a data recovery method which selectively selects only an integrity-checked phase signal, when receiving a backscattered signal of an RFID tag through an I signal path or a Q signal path, and may reduce a shadow area of a read range. The RFID reader includes a signal receiver which receives a plurality of phase signals; a symbol detector which recovers data with respect to each of the received phase signals; and a signal selector which selects a signal that satisfies a predetermined standard, from the data-recovered phase signals.
