摘　　要：采用连续可变斜率增量调制技术和多带激励编码这两种编码方式设计的语音系统是以相应的集成芯片FX609、AMBE-2000在硬件上实现的。芯片TMS320C5402用以对该系统进行软件控制。实验证明,该语音单元使超短波地空电台的各项性能都有了明显改善。A voice processing system,designed by two encoding modes ---CVSD and AMBE,is implemented by their relevant integrated chips---FX609 and AMBE-2000 as hardware,and controlled by the chip TMS320C5402 as software.It has been proved by experiment that the voice processing unit has greatly improved the performance of the ultrashort ground-to-air transmitter-receiver.
