Abstract
A communication device according to the disclosure includes: a signal generator that generates, on the basis of the first signal received from a communication partner through a coil, a second signal that synchronizes with the first signal; a first modulator configured to be able to modulate the first signal on the basis of the second signal; a second modulator configured to be able to modulate the first signal; and a communication controller that selects, on the basis of the first signal, whichever modulator is to be operated, from the first modulator and the second modulator.
Claims33
A communication device comprising:
- a signal generator configured to
- receive a reception signal from a communication partner via a coil, and
- generate a transmission signal based on the reception signal, the transmission signal being synchronized with the reception signal;
- a first modulator configured to modulate the transmission signal;
- a second modulator configured to modulate the reception signal;
- a communication controller configured to select one of the first modulator or the second modulator based on a communication distance from the communication partner to the communication device.
A communication system comprising:
- a first communication device;
- and
- a second communication device including
- a signal generator configured to
- receive a reception signal from the first communication device via a coil, and
- generate a transmission signal based on the reception signal, the transmission signal being synchronized with the reception signal,
- a first modulator configured to modulate the transmission signal,
- a second modulator configured to modulate the reception signal,
- a communication controller configured to select one of the first modulator or the second modulator based on a communication distance from the first communication device to the second communication device.
