PURPOSE: A reception signal processing method in an RFID(Radio Frequency IDentification) reader and RFID using the same are provided to improve the accuracy of reception and reception power by adaptively reducing the calculation number of a digital demodulation operation. CONSTITUTION: A reception unit receives a reception signal from a RFID tag. The reception unit generates the Q signal and I signal of a different phase. A Q-analog-digital converter(265q) changes the Q signal into a digital Q signal from the reception unit. An I-analog-digital converter(265i) changes the I signal into a digital I signal from the reception unit. |
