摘要
使用电话呼叫模拟器对VoFR和VoIP在卫通信道中话音质量进行了系统测试;根据理论分析和测试结果对两种话音质量进行了比较,为卫星通信及长距离、高时延方式下话音传输方式选择提供了重要参考依据。
The simulator of telephone calling system is introduced. After systematic testing of the voice quality on VoFR and VolP through satellite communication, the differences in terms of quality, bandwidth, jitter and so on are compared. A useful reference for the choice of voice transmission through satellite communication of long-distance, high-delay channels is provided.
