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.

Abstract: PURPOSE: A method for operating an interleaver memory is provided to divide a memory area of one interleaver memory into several banks, and to store channel data in blank banks, so as to improve memory use efficiency when a plurality of subscribers access a base station. CONSTITUTION: If a writing operation is requested(1), a micro controller(10) decides a sub modulator and a modulator unit(140)(2), and reads a bank state register of a bank controller(120) to recognize locations and sizes of blank banks(3). The micro controller(10) calculates the number of consecutive blank banks and a bank of a minimum start address(4), and writes data in a bank allocation register(5). The bank state register of the bank controller is set(51). The micro controller(10) respectively stores calculated values in a frame offset register, an address offset register and a spreading factor value register of the modulator unit(140)(6). The micro controller(10) receives channel data for interleaving and sequentially writes the channel data in the blank banks of an interleaver memory(7). A frame controller of the modulator unit(140) generates a frame synchronous signal(61). If the frame synchronous signal is 1(one)(62), a memory read address and control signal generator of the modulator unit(140) generates a read address, a memory selection signal and a read signal(63), and produces a signal for reading the channel data stored in the interleaver memory by referring to the values stored in the registers(64). The channel data are read and provided to each modulator unit(140), then modulated(65). If the channel data stored in the interleaver memory are completely read, the memory read address and control signal generator generates a flag signal to notify the completion of interleaving(66).
