    Abstract: There is provided a frequency selective transmission apparatus. The frequency selective transmission apparatus includes: a preamble generating unit that generates a preamble for frame synchronization; an SFD/RI generating unit that generates a start frame delimiter/rate indicator (SFD/RI) having a function of an indicator to announce the start of the frame and a function to define the transmission rates of a header field or header and data fields; a header generating unit that generates a header including attribute information on transmission data; a data generating unit that has a predetermined processing gain and transmits digital data at a desired frequency band; a pilot generating unit that generates a pilot inserted into the frame for frequency offset compensation; a multiplexer that receives and multiplexes outputs from the preamble generating unit, the SFD/RI generating unit, the header generating unit, the data generating unit, and the pilot generating unit, respectively; and a signal electrode that transmits the output from the multiplexer into a human body.

    Abstract: A method and apparatus for communicating a sound wave is provided. The apparatus includes: a sound wave converter converting a sound wave signal transmitted from a counter apparatus through the human body into an electrical signal when the sound wave is transmitted from the counter apparatus through the human body and converting an electrical signal on data to be output to the counter apparatus into a sound wave; a data processor receiving the converted electrical signal from the sound wave converter and transmitting an electrical signal on the data to be output to the sound wave converter when the data to be output exists; and a switch connected between the sound wave converter and the data processor, the switch transmitting the converted electrical signal to the data processor and transmitting the electrical signal on the data to be output to the sound wave converter. Accordingly, it is possible to efficiently transmit a signal with a low loss of sound wave signal. Thus, it is possible to simply construct communication hardware at a low price.
