Abstract
A new scheme to handle the echo canceller as an on-side job of a LD-CELP codec is studied in the paper. The authors give a novel approach to integrate the echo canceller (CCITT G.165) into the LD-CELP codec, such as CCITT G.728 "Coding of speech at 16 kbps using low-delay code-excited linear prediction" codec.<>
