摘要
由于信息技术的发展和频率资源的日趋宝贵,语音通信朝着多模式、低码率的方向发展.采用高性能的语音编解码芯片AMBE-2000、模数转换芯片AD73311、DSP芯片可以容易地实现低码率的语音通信系统设计,并取得了良好的语音质量.
With the development of information technology and the reduction of available frequency resources,the voice communication is being developed in the trend of multi-mode and low code rate.A voice communication system with low code rate can be easily realized by using AMBE-2000,AD73311 and micro controller,and the quality of the voice is fine.
