Abstract: PURPOSE: A method for converting a vibration mode of a mobile communication terminal by sensing a pilot signal is provided so that a user can easily convert a reception mode without using an additional device, by employing a pilot PN(pseudo noise) signal search function. CONSTITUTION: An RF unit(110) receives an RF radio signal from a base station through an antenna, and demodulates it to a baseband. A search unit(120) searches a pilot of an adjacent base station from the received signal. According to the pilot search operation, a reception mode is converted into a vibration mode. A nonvolatile memory(140) stores nonvolatile data for operating a mobile communication terminal. The data includes system data, and pilot set information such as active group information, adjacent group information and candidate group information. Especially, the adjacent information data includes pilot PN. A nonvolatile memory(150) is operated as an operation memory of the mobile communication terminal, for temporarily storing the data. A key input unit(130) is used as a user information input unit. A control unit(100) controls the whole operation of the mobile communication terminal, and also controls conversion of the reception mode. Therefore, the reception mode can be converted into the vibration mode without the additional manual operation of the user, or additional device by using the pilot PN signal search function.

Abstract: A method for coding or decoding an audio signal combines the advantages of TNS processing and noise substitution. A time-discrete audio signal is initially transformed to the frequency domain in order to obtain spectral values of the temporal audio signal. Subsequently, a prediction of the spectral values in relation to frequency is carried out in order to obtain spectral residual values. Within the spectral residual values, areas are detected encompassing spectral residual values with noise properties. The spectral residual values in the noise areas are noise-substituted, whereupon information concerning the noise areas and noise substitution is incorporated into side information pertaining to a coded audio signal. Thus, considerable bit savings in case of transient signals can be achieved.
