- 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.
