Abstract

In order to realize the low bit rate transformation and storage of the speech signal,this paper introduces the features and basic principles of the G.729 algorithm which is proposed by ITU.And a TMS320C5509-centered real-time coding and decoding system is also discussed.The implementation of hardware and software of the real-time system are described in detail.This real-time communication system can connect with other system through an additive communication module,which realizes realtime speech communication.
