基于E模型的战术综合业务数字网语音干扰效果评估

Jamming Effect Evaluation of Tactical ISDN Based on the E-Model

首先定性分析了战场网络受到干扰时对话音业务通信质量的影响，然后以E模型话音质量评估方法为基础，对话音业务的干扰效果进行了定量评估，并基于语音质量R值进行了相应的干扰等级划分。

The influence to the speech quality for VTOA（ Voice Trunking Over ATM） is analyzed qualitatively when the tactical ISDN（Integrated Services Digital Network） is jammed. Then, based on the E-Model speech quality evaluation method, the jamming effect to speech quality is evaluated quantificationally. At last, the jamming grade is marked off based on the R values of speech quality.
