    Abstract: A receiver in a human communication system includes: receiving electrodes including a transmission frame including control frames and data frames; first and second switches connected with the receiving electrodes; a switching control unit controlling a switching of the first and second switches to selectively connect the receiving electrodes with the first and second switches in response to each control frame according to a predetermined rule every time each of the control frames is input; a signal processing unit performing signal processing on the transmission frame output from the first and second switches; a preamble detection unit detecting the first preamble from each of the control frames included in the signal-processed transmission frame to generate preamble correlation values for the first preamble; and a correlation value processing unit controlling the switching control unit to select pairs of final receiving electrodes among the receiving electrodes based on the preamble correlation values.

    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).

    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.
