Communication system, communication device, wired communication device, and communication method
First Claim
1. A communication system comprising:
- a communication device; and
a wired communication device connected to the communication device by a first connecting line and a second connecting line;
the communication device including;
(a) a first processor;
(b) a first memory device storing first instructions, which when executed by the first processor cause the first processor to;
(i) output a clock;
(ii) generate a resulting modulated signal by performing amplitude shift keying modulation on the clock using a modulation subject signal to be sent to the wired communication device;
(iii) output, via the first connecting line, the resulting modulated signal to the wired communication device; and
(iv) communicate with a near field communication device that performs near field communication in at least one of an active mode and a passive mode, the near field communication device being different from the communication device and the wired communication device;
the wired communication device including;
(a) a second processor;
(b) at least one of a subscriber identity module and a user identity module; and
(c) a second memory device storing second instructions, which when executed by the second processor cause the second processor to;
(i) extract the clock from the modulated signal sent from the first connecting line;
(ii) extract the modulation subject signal from the modulated signal sent from the first connecting line;
(iii) process the modulation subject signal in accordance with the extracted clock; and
(iv) output, via the second connecting line, the processed modulation subject signal to the communication device.

Abstract
A communication system includes a wired communication device and a communication device that can communicate with a wireless communication device and the wired communication device. The communication device includes a clock output unit and a modulator. The wired communication device includes a clock extracting unit, a signal extracting unit, and a processing unit. The communication device and the wired communication device are connected to each other by a first connecting line through which a modulated signal is sent from the communication device to the wired communication device, and a second connecting line, which is different from the first connecting line, through which a signal is sent from the wired communication device to the communication device.
