| 摘 要： | 本文在研究ISDN(综合业务数字网络)及ATM(非同步传送模式)网络中语音传输系统时,为了取得较高的语音质量。采用了CCITTG72.x草案推荐的SB-ADPCM(分频带自适应差分脉冲编码调制)技术。实现了7KHz带宽的语音压缩编码器。其中SB-ADPCM算法采用了高性能的单片机系统Transputer构成并行流水线网络,较为灵活地实现了此宽带编码器。并为语音会议系统的实现提供了技术支持。

| Abstract: | In the study of ISDN(Integrated Service Digital Network)and ATM(Asynchronous Tranfer Mode)network,the SB-ADPCM(Sub- Band Adaptive Differential Pulse Code Modulation)technique recommended by CCITTG72.X has been used in this paper,in order to obtain voice compressed encoder of bandwidth 7 kHz.In the SB- ADPCM algorithm,parallel pipelined network constructed from high quality single chip transputers has been used to implement this wide band encoder,which can act as a technical support to the voice conference system. |
