摘要

讨论和分析了在时分多路复用器(TDM)中语音和数据的综合传输。系统以帧格式运行，信道容量由帧大小决定。用于传输语音和数据的信道容量的分配由控制器执行。采用了数字语音插值和嵌入式编码技术，提高了传输效率，便于多路复用的实现。采用动态规划的方法，提出了一种共同优化语音/数据性能的容量分配策略。数值结果表明，在语音质量略有下降的情况下，系统的总吞吐量可以得到提高。

Capacity allocation for integrated voice/data transmission at a packet switched TDM

The integrated transmission of voice and data at a time-division multiplexer (TDM) is discussed and analyzed. The system operates in a frame format and the channel capacity is governed by the frame size. The allocation of channel capacity for the transmission of voice and data is performed by a controller. Digital speech interpolation and embedded coding techniques are used to enhance the transmission efficiency and to facilitate the implementation of multiplexing. Using a dynamic programming approach, a capacity allocation policy that jointly optimizes the voice/data performances is introduced. Numerical results indicate that the aggregate throughput of the system can be improved with a slight degradation in voice quality.<>
