摘要
随着战术互联网等军用网络技术的迅速发展,军用网络电话(VoIP)技术成为近来语音处理与通信领域的一个研究热点。针对军事通信的特点,对VoIP在战场网络环境下的应用进行了有益的探索。介绍了VoIP的概念、原理,研究了战场网络环境下影响VoIP语音质量的主要因素并分析了其对语音质量影响的方式和程度,在此基础上提出了解决军用VoIP语音质量问题的方案:语音编码、丢包处理和抗抖动缓冲。
With the rapid development of military network technologies such as tactical Internet,military VoIP technology currently becomes a hotspot in the research of speech processing and communication.Based on military communication features,a valuable exploration on VoIP application in the battlefield environment is done,and the concept and principle of VoIP described.The main factors which affect the voice quality of VoIP in the battlefield network are analyzed,and how these factors degrades the voice quality is also studied.Based on these,the solutions in overcoming the unfavorable factors are proposed,including speech-coding,packet-loss handling,and anti-jitter buffering.
