Abstract  Abstract

(57) A gain smoothing method and device modifies the amplitude of a novel code vector in relation to background noise present in a previously sampled wideband signal. A gain smoothing device is a gain smoothing for calculating a smoothing gain according to a coefficient representing voicing of a sampled wideband signal, a coefficient representing the stability of a set of linear prediction filter coefficients and a novel codebook gain. Includes a calculator. The gain smoothing device also includes an amplifier for amplifying the novel code vector with the smoothing gain, thereby generating a gain-smoothed novel code vector. The function of the gain smoothing device improves the perceptual composite signal when background noise is present in the sampled wideband signal.
