Abstract :
In this paper, a new variable bit-rate code excited linear predictive (CELP) coder of average bit rate around 4 kbps is presented. The new coder is based on the fedral standards FS 1016 CELP coder. Three main differences between this new coder and the FS 1016 coder are introduced. These three modifications result in reducing the bit rate by about 0.8 kbps.
