Abstract: PURPOSE: A symbol synchronization apparatus and method of a passive RFID reader are provided to increase the reliability in a symbol synchronization operation which may change anytime according to the operating environment of a passive RFID reader. CONSTITUTION: An edge clock detector(50) generates an edge clock by detecting a reception signal and a phase shift position. A preamble detector(60) analyzes the generation time of the edge clock to detect a preamble section. If the preamble section is detected, a symbol determination timing extractor(70) extracts symbol determination timing by averaging the distance between continuously-generated edge clocks in the preamble section.
