摘　　要：介绍了一种数字通信系统的设计思想及其关键技术的实现方法。该系统分为有线通信系统和无线通信系统2个子系统,并将无线通信和有线通信有机地结合在一起,融合为一套有线、无线共存互通的综合通信系统。对系统的各个关键技术做了详细介绍,拼弃了以往设计采用套片的设计思路,关键技术在FPGA内部自主设计。有线部分采用PCM编解码,无线部分采用AMBE话音压缩和RS纠错处理。该系统设计稳定、话音清晰,便于生产和使用。The paper introduces the design ideas and implementation methods of key technologies of a digital communication system. The system is composed of such two subsystems as wired communication system and wireless communication system. The wireless communication and wired communication organically integrated into one integrated communication system in which wired parts and wireless parts co-exist and intercommunicate. Various key technologies in this system are introduced in detail. Not chipset but FPGA is used in the implementation of key technologies. PCM code is used in the wired parts and AMBE voice compression and RS error correction are used in the wireless parts. The system has reliable design and clear voice for convenience of production and use.
