COMMUNICATION DEVICE, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD

摘要

There may be included: a demodulation section configured to perform, based on a modulated signal transmitted from an associated communication device, amplitude change demodulation and phase change demodulation, and configured to select a demodulated signal demodulated with either one of the amplitude change demodulation and the phase change demodulation; and a modulation section configured to modulate magnetic field generated by the associated communication device.
