  • Method and device for phase calibration with active load modulation
    Patent number: 10019608
    Abstract: 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.

  • Pulse shaping for radio frequency transmitters
    Patent number: 9742443
    Abstract: Transients caused by load modulation can fee compensated far by adjusting pulse shapes. A radio frequency (RP) carrier signal can be modulated using load modulation. For the modulated RF carrier signal a particular pattern can be detected for a symbol period that precedes a second symbol that does not use load modulation. In response to the detecting, a pulse shape of the first symbol can be adjusted to mitigate the transients.
