Implementation Of G.729 And Research On Voice Over ATM

ABSTRACTITU-T Recommendation G.729 was a 8kbit/s speech codec approved by International Telecommunication Union in 1996. In this paper,we give a detail discussion on the key technology ,including software and hardware designing of G.729a multi-channel speech codec′realtime implemention on a simple DSP processor- TMS320C6202.In combination with the requirements of a military communication network ,the ATM adaptation solution of G.729 coder′bit stream is analyzed.A kind of new ATM adaptation technology-AAL2 is introduced.The analyse and research of AAL2 are provided. The combination of advantage in the two technology can solve the problem of transmission QOS and bandwidth limitaion of wireless relay network.
