【摘要】 介绍了软件无线电系统的评价标准，这种评价标准主要是指系统的“软件”程度。还介绍了软件可重用性的实现，即要求软件代码能够应用于不同的软件无线电硬件平台中，这要求为软件无线电定义一套专门的软件标准。给出了在“八六三”项目所采用的一种基于异步传输模式（ Ａ Ｔ Ｍ）交换网络的软件无线电的硬件平台，它具有很好的开放性、可扩展性和可重构性，它能够灵活的配置成为不同功能的软件无线电应用系统。它较之目前国内外讨论较多的总线式结构有明显的优势。最后给出了具体实现上述硬件平台的一种环形结构更多还原

【Abstract】 An evaluation criterion of software radio was introduced, which focus on the “soft” degree of a software radio system. Next the realization of software reuse in software radio was described, which needs a special software standard for software radio. Then new idea on hardware platform of software radio was presented, which is based on asynchronous transfer mode (ATM) switched network. This architecture is very open, scalable, and configurable. It can be configured to realize various software radio application systems. It has many advantages compared with the conventional bus architecture. Finally a circular architecture to realize the switched network is proposed.更多还原
