Abstract:

This paper describes how fractal predictive coding can be used in speech coding. First the IFS theory, on which fractal coding is based, is presented. Then, the coding algorithm is described and its performance is compared with the ADPCM coder G.726. Next, some perceptual considerations are introduced, which allow better performance at lower bit rates, obtaining good results at 16 kb/s. Finally, the use of this algorithm is evaluated in wideband speech coding, giving good performance at 32 kb/s.
