1.系统 1.1 设计方法 1.1.1 工作原理语言插入系统的基础是传输谈话中单个发生的语言突发。系统活动率由话音突发持续时间和频率决定。在通常的话音传输中,电路接通时,一条话音信道只有30％到40％的时间是活动的,其余时间就能为其他信道的话音传输所用。适当利用这种性能,就能大大增加通信系统的容
1. System 1.1 Design Methodology 1.1.1 How It Works The foundation of a language insertion system is the transmission of a single occurring language burst in a conversation. The system activity rate is determined by the voice burst duration and frequency. In normal voice transmission, when a circuit is switched on, only 30% to 40% of the time of a voice channel is active and the rest of the time can be used for voice transmission of other channels. Appropriate use of this performance, we can greatly increase the capacity of the communication system
