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 8):
A radio-frequency identification (RFID) reader for obtaining a backscatter modulated signal, comprising:\n a local oscillator configured to provide a carrier wave; a transmit signal generation device configured to generate a transmit signal based on the carrier wave and an input signal; a transmitter configured to transmit said transmit signal; a receiver configured to receive a backscatter modulated receive signal in response to the transmit signal; a combiner configured to combine the receive signal with a cancel signal to obtain a corrected receive signal; and a processor configured to determine a phase shift and an amplitude adjust from the corrected receive signal; wherein the transmit signal generation device comprises a phase shifter, which is configured to apply the determined phase shift as a phase rotation when generating the transmit signal; and wherein an attenuator is configured to generate the cancel signal based on the un-shifted carrier wave and the determined amplitude adjust.
