Abstract:
An example method for active load modulation includes determining a modulated portion and an unmodulated portion of a bit. Further, the example method includes during the modulated portion of the bit, holding a phase of a received carrier signal. In addition, the example method includes, during the unmodulated portion of the bit, synchronizing to the received carrier signal.
