    摘要: The present invention provides a communication apparatus being in directly contact with a human body and using the human body as a transmission channel for data communication. The communication apparatus attached to the human body transmits a signal in the form of a current, receives a signal transmitted from another communication apparatus attached to the human body therethrough, and eliminates noise included in the received signal. In addition, the communication apparatus compares the noise-eliminated signal and a reference signal and recovers an original signal. Further, the communication apparatus generates a base-band signal and transmits the same through the human body.

    摘要: Provided is a human body communication method using a multi-carrier modulation method, in which users do not interfere with each other in an environment with several users, and stable communication is possible when users are exposed to strong interference generated at other electronic devices. Also, provided are a multi-carrier modulation method, in which data between communication devices connected to a human body used as a channel is divided into a plurality of sub-channels and the data is transmitted by loading it on each of a plurality of sub-carrier signals, and a multi-connection method using the multi-carrier modulation method. The plurality of sub-channels having a predetermined bandwidth include several sub-carriers, and by changing a modulation method applied to the sub-carriers, stable communication can be realized.
