| Abstract: | In recent years, considerable interest has been focused on VoIP system. In this paper, the delay and echo of the VoIP system is first discussed, in IP network, and then, the basic echo cancellation algorithm is reviewed. Finally, the estimation of delay in IP network is used to enhance echo cancellation. |
