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.

PURPOSE: A human body communication apparatus allowing noncontact and a human body communication method allowing noncontact in the apparatus using frequency selective baseband are provided to remove the interference among users by using a restricted frequency band for which a inductive electromagnetic filed characteristic and a human body delivery characteristic are most efficient. CONSTITUTION: A human body communication transmitter(120) distributes transmitting data based on frequency-selective spreading code through a frequency-selective baseband. After multiplexing with a header, the human body communication transmitter outputs the transmitting data as a transmitting signal. An antenna(150) transmits the amplified transmitting signal of a signal processing unit based on the contact or non-contact with a human body to a communication device via the human body.
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.
