摘要 提出了一种基于自适应多速率算法的新VoIP系统方案,该方案可以根据网络信道质量的好坏来自适应地选择一种最佳的语音传输模式,从而在一定程度上保障了重构后的语音质量。在NS-2仿真平台下,通过与传统VoIP体系比较发现,所提出的新VoIP系统方案在语音QoS保障方面明要显优于传统VoIP系统。 This paper presents a new VoIP system based on AMR algorithm, which can adaptively choose a best transfer mode to transmit voice according to the quality of network channel. In the NS-2 platform, by comparing with the traditional VoIP system, the proposed new VolP system is founded to be better on QoS.
