Abstract:
There is provided a human body communication method and system using a frequency-selective baseband in order to transmit and receive data between communication devices that are coupled to a human body by using the human body as a communication channel. The human body communication method and system may be useful to maximize an efficiency of the frequency-selective spreading technology to enhance a processing gain of the Walsh code technology, and thus to reduce the interference between human bodies of users by adaptively selecting a frequency band of Walsh codes that are used for data communications according to the human body channel characteristics and the noise environments that are varied according to the ambient environments, and also construct a low-power and stable human body communication when there is a strong interference induced from other electronic equipments.

Abstract:
There is provided a communications system and method using a part of human body as an antenna in a body area network, and more particularly, to a communications system and method enabling wireless communications using a low frequency band without the use of a bulky antenna in such a manner that a transmitting-side communications device applies electrical signals to a human body via a transmitting-side coupler to allow a part of human body to act as an antenna, and electrical signals, occurring in another part of human body due to radio frequency (RF) signals, are transferred to a receiving-side communications device via a receiving-side coupler.
Abstract:
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.
Abstract:
Provided are a system and method for human body communication using a limited passband. The system includes a transmission frame generating unit for human body communication which generates a transmission frame for human body communication based on data information including user identification (ID) and data scrambled into an orthogonal code generated by the user ID; a symbol mapping unit for symbolizing the generated transmission frame for human body communication according to a predetermined modulating method; a spreading unit for spreading the symbol outputted in the symbol mapping unit; a waveform generating unit for generating a baseband signal whose band is limited to a predetermined range with respect to the data spread in the spreading unit; and a middle band transmitting unit for modulating the baseband signal into a predetermined limited passband signal.
