Patent number: 10019608Abstract: A method for operating an RFID device is disclosed. In the embodiment, the method involves establishing a radio-frequency link, receiving signal samples of the radio-frequency link, determining the offset of an initial phase of the link by filtering noise from the signal samples, windowing the filtered signal samples, and calculating an offset value from phase differences between the windows of signal samples, and modifying a configuration profile based on the offset value. During data transmission the configuration profile can be used to configure the transmitter in order to maintain the constant phase during transmission.Type: GrantFiled: December 9, 2015Date of Patent: July 10, 2018Assignee: NXP B.V.Inventors: Ulrich Neffe, Hubert Watzinger, Michael Stark, Johannes Bruckbauer, Thomas Noisternig
