Abstract: PURPOSE: A multifunctional mobile terminal having a broadband voice encoder function and a DAB(Digital Audio Broadcasting) receiving function is provided to add a broadband voice encoder function, a DAB receiving function, and an MP3 player function to a mobile terminal. CONSTITUTION: A multifunctional mobile terminal comprises the first and second antennas(ANT1.ANT2), a mobile communication RF part(100), a DAB RF part(200), a terminal central processing part(300), a voice codec(400), an MPEG layer II/III decoder(500), a voice band codec(600), an audio DAC(Digital Analog Converter)(700), and an analog signal input/output part(800). The first and second antennas(ANT1.ANT2) transmit and receive mobile communication data and DAB data respectively. The mobile communication RF part(100) and the DAB RF part(200) execute RF signal processing for mobile communication data and DAB data respectively. The terminal central processing part(300) controls the overall operations of the multifunctional mobile terminal. The voice codec(400), if packet data are supplied from the terminal central processing part(300), regenerates a digital voice signal and transfers it to the voice band codec(600). In case that a digital voice signal is provided from the voice band codec(600), the voice codec(400) compresses the digital voice signal and supplies it to the terminal central processing part(300). The MPEG layer II/III decoder(500) regenerates a digital audio signal from the MP2 or MP3 packet data transmitted from the terminal central processing part(300) and outputs it to the audio DAC(700).

Abstract: PURPOSE: An apparatus for reproducing a multi-channel stereo sound and a method for the same are provided to prevent the power consumption due to the reduction of the calculation amount as well as to reduce the deterioration of the sound quality. CONSTITUTION: An apparatus(100) for reproducing a multi-channel stereo sound includes a main controller(120), a threshold setting block(130), a threshold resetting block(140), a signal level measuring block(150), a stereo sound signal processing block(160), a signal synthesizing block(170) and an audio output block(180). The main controller(120) synthesizes the multi-channel audio data inputted from outside with at least two audio data in response to the measured noise level and the selection of the user to reproduce. The threshold setting block(130) sets a threshold value in response to the selection of the user. The threshold resetting block(140) resets the threshold value based on the measured noise level in response to the update of the user. The signal level measuring block(150) measures the signal levels of each multi-channel audio data inputted from the outside. The stereo sound signal processing block(160) processes the inputted audio data as a stereo sound in response to the measured signal level and the reset threshold. The signal synthesizing block(170) synthesizes the signal processed multi-channel data as an audio data having at least two channels. And, the audio output block(180) outputs the synthesized audio data to outside.

Abstract: An apparatus for estimating location of terminal, after receiving the information on definite locational information of the terminal, estimates the location of the terminal by the dead reckoning using the definite locational information ultimately received if the definite locational information of the terminal is not obtained within the set time period. In addition, if the location information of the closest terminal using a dead reckoning is more credible than the location information of the terminal of the present invention, the definite locational information of the terminal as well as the positioning information of the closest terminal are manifoldly incorporated to estimate an incorporative location information.
