Abstract: Methods and apparatuses are provided for cell reselection at a mobile terminal. A first cell measurement is performed with respect to a serving cell and a first set of one or more cells included in a neighbor cell list. A second cell measurement is performed to detect a second set of one or more cells that are not included in the neighbor cell list, based on the first cell measurement. One or more candidate cells that satisfy cell reselection criteria are determined from among the first set of one or more cells and the second set of one or more cells. One of the one or more candidate cells is reselected.

Abstract: In a voice coding and decoding method and apparatus using an RCELP technique, a CELP-series decoder can be obtained at a low transmission rate. A voice spectrum is extracted by performing a short-term linear prediction on voice signal. An error range in a formant region is widened during adaptive and renewal codebook search by passing said preprocessed voice through a formant weighting filter and widening an error range in a pitch on-set region by passing the same through a voice synthesis filter and a harmonic noise shaping filter. An adaptive codebook is searched using an open-loop pitch extracted on the basis of the residual minus of a speech. A renewal excited codebook produced from an adaptive codebook excited signal is searched. Finally, a predetermined bit is allocated to various parameters to form a bit stream.
