Abstract:
The disclosed subject matter relates to a method for obtaining a backscatter modulated receive signal in an radio-frequency identification (RFID) system, comprising the steps: providing a carrier wave by a local oscillator; generating a transmit signal based on the carrier wave and an input signal; transmitting said transmit signal; receiving a backscatter modulated receive signal; and combining the receive signal with a cancel signal; wherein the method further comprises the step of determining a phase shift and an amplitude adjust from the corrected receive signal; wherein the determined phase shift is applied as a phase rotation when generating the transmit signal; and wherein the cancel signal is based on the un-shifted carrier wave and the determined amplitude adjust. The disclosed subject matter further relates to an RFID reader configured to perform said method.

Claim (Index 15):
The RFID reader according to  claim 8 , wherein a downconverter is arranged between the combiner and the processor, wherein the downconverter is configured to receive the carrier wave from the local oscillator or the phase shifted carrier wave from the phase shifter to downconvert the corrected receive signal.
