Abstract :
A new signal process based on a nonlinear local prediction model (NLLP) is presented and applied to speech coding. With the same implementation, the speech coding based on the NLLP gives improved performance compared to reference versions of the standard ITU-T G.728 and linear local scheme. The computational efforts for the NLLP analysis does not increase over the conventional linear prediction (LP), and the NLLP supplies better prediction performance over the LP and linear local prediction
