Signal processing method of reader of RFID

摘要

PURPOSE: A signal processing method of an RFID(Radio Frequency IDentification) reader is provided to effectively simplify the circuit and operation for processing channel signals. CONSTITUTION: A termination receiving signal generating unit gradually couples channel signals(S26). The termination receiving signal generating unit compares signal strength of a coupled result signal with signal strength whenever the channel signals are coupled(S22). When the signal strength is stronger than the reference strength, the termination receiving signal generating unit ends coupling. The termination receiving signal generating unit generates the coupling result signal as the termination receiving signal(S23).
