    摘要: An apparatus and method for eliminating cross-talk being heard at a listener device in a mobile communication system. The apparatus eliminates cross-talk occurring in a signal output through at least two speakers in a mobile system, and includes a decoder for decoding an input signal, a controller for providing information about a delay time difference between direct sound and cross-talk sound of the input signal and gain variation information, a cross-talk cancellation unit for receiving the delay time difference information and the gain variation information and eliminating cross-talk from the decoded signal received from the decoder, and an output unit for converting a stereo signal, from which the cross-talk has been eliminated, into an analog signal and outputting the analog signal through the at least two speakers.

    摘要: Disclosed is an apparatus and a method for enabling sound data having a three dimensional stereo sound effect to be reproduced in a mobile communication terminal. A three dimensional stereo sound reproducing apparatus for a mobile communication terminal comprises: a memory for storing sound data having a three dimensional stereo sound effect; a sound processing unit for reading the sound data from the memory when an incoming call is generated or when a user requests reproduction of the sound data and for decoding the sound data without distortion of the three dimensional stereo sound effect, thereby outputting the sound data as a type of an analog signal; and a speaker for amplifying the analog signal and outputting the amplified analog signal as a type of an audible sound. Therefore, it is possible to obtain an excellent three dimensional stereo sound effect and an excellent performance in reproducing original sound.
