| Abstract: | In order to realize the low bit rate transformation duces the features and basic principles of the G.729 TMS320C5509- centered real - time coding and decoding and storage of the speech signal, this paper introalgorithm which is proposed by ITU. And a 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 real - time speech communication. |
