1. A communication device, comprising:
- a signal generator that generates, on a basis of a reception signal received from a communication partner through a coil, a transmission signal that synchronizes with the reception signal;
a first modulator configured to modulate the transmission signal;
a second modulator configured to modulate the reception signal; and
a communication controller that selects, on the basis of the reception signal, whichever modulator is to be operated, from the first modulator and the second modulator.

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.

18. A communication method, comprising:
-
receiving, with a coil, a reception signal from a communication partner; selecting, with a communication controller, one of a first modulator or a second modulator based on the reception signal, the first modulator being configured to modulate a transmission signal, and the second modulator being configured to modulate the reception signal; and responsive to selecting the first modulator, generating, with a signal generator, the transmission signal based on the reception signal, the transmission signal being synchronized with the reception signal.

19. A communication method, comprising:
-
receiving, with a coil, a reception signal from a communication partner; selecting, with a communication controller, one of a first modulator or a second modulator based on the reception signal, the first modulator being configured to modulate a transmission signal, and the second modulator being configured to modulate the reception signal; responsive to selecting the first modulator, generating, with a signal generator, the transmission signal based on the reception signal, the transmission signal being synchronized with the reception signal; adjusting a phase of the transmission signal based on the reception signal; and modulating, with a first modulator, the transmission signal having an adjusted phase.
