RFID DEVICE, RFID SYSTEM AND EQUALIZATION PROCESS IN RFID SYSTEMS

摘要

In an RFID system an RFID device (2) comprises a device air interface (C2) with a predefined quality factor (Q2) for receiving wireless data signals (DS) being sent by a remote RFID transponder (1) comprising a transponder air interface (C1) with a predefined quality factor (Q1), and data signal processing means (4) for processing the data signal (DS) received by the device air interface (C2).Data signal equalization means (3) are arranged between the device air interface (C2) and the data signal processing means (4), wherein the data signal equalization means (3) are adapted to compensate signal distortions of the data signals (DS) caused by the quality factors (Q2, Q1) of the device air interface (C2) and the transponder air interface (C1) of the RFID device (2) and the RFID transponder(1), respectively.
