Abstract
for correcting the innovation code vector amplitude gain smoothing method and device with the background noise previously sampled wideband signal. gain smoothing device comprises a factor response represents a sampling of the sound in the broadband signal and represents a set of stability of linear prediction filter coefficient factor calculating a smoothed gain and the innovation codebook gain of gain smoothing calculator. The gain smoothing device further comprises one of a smooth gain to amplify the innovation code vector so as to produce amplifier gain smoothing of the innovation code vector. the function of gain smoothing device improves the quality of the perceived background noise under the condition of synthesizing signal exists in sampling the broadband signal.
The gain smoothing method and device modify the amplitude of an innovative codevector in relation to background noise present in a previously sampled wideband signal. The gain smoothing device comprises a gain smoothing calculator for calculating a smoothing gain in response to a factor representative of voicing in the sampled wideband signal a factor representative of the stability of a set of linear prediction filter coefficients and an innovative codebook gain. The gain smoothing device also comprises an amplifier for amplifying the innovative codevector with the smoothing gain to thereby produce a gain-smoothed innovative codevector. The function of the gain-smoothing device improves the perceived synthesized signal when background noise is present in the sampled wideband signal.
