Abstract: PURPOSE: A selective frequency modulating apparatus using a re-spreading code and a method thereof are provided to use an orthogonal code with a high spreading rate, thereby increasing the processing gain of the entire system. CONSTITUTION: A serial-parallel convertor converts transmission data serially or in parallel according to a preset ratio. At least one sub frequency selective spreading device(121~123) selects one spreading code using a data bit inputted from the serial-parallel convertor. A multi value selecting unit(130) selects multi values in at least one spreading code. The first XOR logic circuit(140) re-spreads a selective frequency baseband into a selective frequency transmitting band by XOR-operating the output of the multi value selecting unit with a re-spreading code, Wn.

Abstract: A chair and a multimedia playing device are provided to listen to a sound signal through a simple contact operation of user. A sound transmitting device(100) restores a sound signal around an ear of a human body after generating a demodulation signal for demodulating a sound signal from a synchronization signal and the synchronization signal including the sound signal. If user is contacted with a surface of a chair, the sound transmitting device transmits the sound signal. The sound transmitting device is positioned in a surface of a back cushion part contacted with a back of user, or is positioned in a surface of a seating part contacted with a thigh of user. The sound transmitting device includes a first sound transmitting part(100a) and a second sound transmitting part(100b). The first sound transmitting part synchronizes the sound signal to a high frequency signal, and outputs the synchronization signal to a human body. The second sound transmitting part outputs a demodulation signal for offsetting the high frequency signal to the human body.

Abstract: An apparatus and a method for transmitting a sound through nonlinear media are provided to reduce power consumption by using one transmitting signal through one transmitting device. A pre-distorter(101) pre-distorts a sound signal(a(t)) of an audible frequency band by considering a frequency property of a transmitting part(104) and a nonlinear medium(105). A sigma-delta modulating part(102) modulates the distorted sound signal(s(t)) into a signal(M(t)) having two signal levels. The sigma-delta modulating part processes the signals by a frequency larger than twice of bandwidth of the sound signal. A high frequency modulating part(103) generates a high frequency modulating signal(p(t)) by multiplying a carrier signal having a frequency higher than an audible frequency by an output signal of the sigma-delta modulating part. The transmitting part converts the high frequency modulating signal into a sound wave signal.

Abstract: A method and an apparatus for communicating a sound wave of a human body are provided to simply and efficiently communicate data among apparatuses contacting the human body by using a phenomenon of transmitting the sound wave through the human body. A sound wave converter(120) connected to an input/output unit(110) converts an electrical signal of output data into a sound wave, applies the sound signal to a human body(10), and converts the sound wave transmitted through the human body into an electrical signal. Here, the sound wave signal applied to the human body is transmitted from a part of the human body which contacts a first apparatus for communicating the sound wave of the human body to a part of the human body which contacts a second apparatus for communicating the sound wave of the human body and input into the second apparatus for communicating the sound wave of the human body. Since the input sound wave signal is converted into an electrical signal, again, data is communicated between the first and second apparatuses for communicating the sound wave of the human body. A switch(130) is connected to the sound wave converter and input and output ports of a data processor(140). The switch switches the input/output data by changing the switch to the input port or output port in response to a control signal generated by the data processor. In a case where there is data to be transmitted, the data processor outputs a data signal having an analog or digital form to the output port in an electrical signal form. At this time, the data processor generates a control signal and changes the switch so as to connect the output port to the sound wave converter. In addition, in a case where there is a sound wave signal to be transmitted through the human body, the data processor generates a control signal and changes the switch so as to connect the data processor to the input port. The sound wave converter receives the converted electrical signal. The apparatus for communicating the sound wave of the human body according to the first embodiment of the present invention communicates data through the human body.
