摘　　要：随着战术互联网等军用网络技术的迅速发展,军用VoIP技术成为近年来语音处理与通信领域的一个研究热点。文章以能够提高IP语音质量的抗抖动缓冲技术为研究重点,介绍了抗抖动缓冲的原理并对现有的自适应缓冲算法进行了分析和比较,然后提出了一种基于E-Model的自适应缓冲算法,实验结果表明此算法比其他缓冲算法拥有更好的抗抖动性能。With the rapid development of network technology such as Tactical Internet, tary VoIP technology has recently become a focus in the research of speech munications. Focusing on the de-jitter buffering technology which is one of processing and corne key technologies to improve voice quality in VoIP, the principle of de-jitter buffering mechanism was introduced and the features of existing adaptive buffering algorithms compared. Then, an adaptive buffering algorithm based on E-Model was proposed. Simulation results show that this new algorithm has better performance than the existing adaptive buffering algorithms.
