Implementation Of CS-ACELP Algorithm On TMS320C54X

As a very important part of information transport in multimedia communication, Speech coding attract more and more attetion.For utilizing the limited bandwidth enough and for offering high quality multimedia service in all kinds of place, people researched a low bit rates and without quality degradation for a long time . In 1996, codeing of speech at 8kbit/s using CS-ACELP was standardized as Recommendation G. 729. It is expected to be used for 3G Personal Handy-phone System as standard algorithms which encode speech signals and decode it.Additionally, this kind of algorithms which own excellent quality can be application in viewphone and video order programme etc. The thesis introducethe algorithm structure of G. 729. And add c source code of G. 729 to VC++ programs which I developed , so I can tell from whether the input speech is same with output. 1 performs this Recommendation with TMS320C54X DSP and optimize it.
