| Abstract: |
| This paper introduces the vocoder applied in CDMA systems. With a model of CDMA2000 system based on IP, it describes the transmission and control of voice, then discusses the control method of vocoder applied in all kinds of control models of operation stream. It shows that this system saves vocoder resource and simplifies signaling flow and improves operation quality. |
