软件无线电技术在卫通终端中的应用

Software Radio Terminal for Satellite Communication

根据软件无线电技术的思想,提出了一种依托通用的可编程硬件平台,以各种软件模块实现不同标准信号通信的多速率、多模式的卫星通信终端的设计。详细讨论了该设备的软、硬件结构设计,并对所涉及的开放式的总线结构、宽带A/D、D/A转换技术、高速数字信号处理技术、功能软件模块化编程设计等关键技术进行了分析。

The paper puts forward a design idea by using software radio technique, designing multi-rate and multi-mode satellite communication terminal based on a general programmable hardware platform and various software modules to implement different functions. A discussion about software and hardware structure of the system is described. Analysis of key technologies, such as open bus structure, broadband A/D and D/A, high speed DSP and modular design of functional software, are also given.
