摘　　要：In this paper, the authors present a method to handle the Echo Canceller as an on-side job of LD-CELP codec and a circuitry to embed echo canceller into a LD-CELP codec. The Possibility to implement a system with the integration of LD-CELP codec and echo canceller in real time by two chips of TMS320C30 isdiscussed.In this paper, the authors present a method to handle the Echo Canceller as an on-side job of LD-CELP codec and a circuitry to embed echo canceller into a LD-CELP codec.
