The Implementation of ITU-T G·729 Speech CODEC Using DSP

Jingxin Hong

Abstract

After studying the principle of ITU-T G·729 in detail, some optimized methods are presented according to the characters of the algorithm and DSP, which can reduce the calculation burden. Its implement scheme founded on the hardware system composed of DSP TMS320VC5410 is also presented. This design can be widely used in the digital voice storage system and network multimedia communication system.
