自适应多路增量调制技术——一种扩大通信容量的方法
An Adaptive Multichannel ΔM ——A Method of Increasing Channel Capacity
【摘要】 本文报导自适应多路增量调制技术研制情况。首先简要回顾话音插空技术。其次阐述本方案的工作原理,及其与话音插空技术的关系。第三讨论某些重要问题及其解决的方法。最后给出12路实验机的现场实验结果。应用本方案,多路数字电话的容量约可扩大一倍,而话音质量尚可。
【Abstract】 In this paper, the development of an adaptive multichannel AM is reported. Firstly, the speech interpolation technique is briefly reviewed. Secondly, the principle of operation of this scheme is described and its relationship to speech interpolation is pointed out. Thirdly, some important problems and their possible solutions are discussed. Lastly, the field test results of an experimental 12-channel system are presented. By way of this method, the capacity of multichannel digital telephone system can be almost doubled with fairly satisfactory performances.
