    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.

    Abstract: PURPOSE: An RFID system using human body communication is provided to remarkably reducing the power consumption of a reader and a tag. CONSTITUTION: A first electrode pad receives a signal of a reader(320) transmitted from a body and outputs an output signal to the body. A modulator and a demodulator modulate the output signal of a tag(310) and demodulate the signal of the reader. A digital controller performs the reading and writing operations by responding to the modulated signal of the reader. A coil is connected between the first electrode pad and the second electrode pad. When the tag is operated in a first operation mode, a mode selector connects the second electrode pad with a rectifier. In case that the tag is operated in a second operation mode the mode selector releases the connection between the second electrode pad and the rectifier.

    Abstract: PURPOSE: A decoding method based on list sphere decoding is provided to lower computational complexity by reducing the calculation number of a Euclidean distance in decoding based on a list sphere decoding technique. CONSTITUTION: The m-numbers of predetermined candidate vectors are selected by using a list sphere decoding technique in a communication system having the n-numbers of transmission-reception antennas(S110). An additional candidate vector is selected by selectively mixing one from the (N-1) numbers of the symbols included in each candidate vector and the symbol located around each candidate vector on a signal-space diagram for the n-numbers of each candidate vector(S120). The m-numbers of the candidate vectors, having a Euclidean distance closest to a reception vector, are successively selected from a vector set which is determined according to the n-numbers of the transmission-reception antennas and a modulation order(S20).
