【摘要】:软件无线电是一种新兴的无线电广播通信技术,其核心思想是在一个通用的、标准的、模块化的硬件平台上用软件来实现无线电台的各种功能。具体实现上来讲,可通过下载和更新软件来升级频带信息、接口协议和功能等,通过动态加载新的波形和协议,它能够重新编程或配置,以此来实现不同的应用。本文针对上述理论,结合当今的硬件工艺水平和数字信号处理技术,以可实现为出发点,设计了一种可重构的数字信号处理系统,该系统采用开放的VPX架构,将组成该平台的各种组件或元素以搭积木的方式拼凑组合,通过软件配置实现不同的应用。本平台的核心是中频信号处理模块,在实际应用中以中频信号处理主板搭载FMC子卡的方式提供支撑丰富的外围接口,同时在模块的设计过程中通过对I/O模块、数据处理模块等进行模块化的处理,以达到可同时使用于多个项目的目的。本文主要做了以下工作:1、研究了软件无线电、数字信号处理的基本理论,对可重构技术、VPX总线技术等进行了重点研究;2、在对可重构技术的深入理解下,设计出一种基于VPX架构的可重构高速信号处理平台的实现方案,对其平台组成、系统功能以及架构设计等做了详细阐述;3、完成中频信号处理主板的设计和实现,包括主板的设计思想、基本架构、主要器件的选型、主板的原理图详细设计;4、完成FMC子卡的设计和实现,包括子卡的结构要素设计、主要器件的选型、FMC子卡的原理图设计和PCB设计;5、搭建可重构平台,对中频信号处理模块和该平台的软件可重构性进行了测试和验证。本文的研究工作主要基于实际项目,已经应用于各课题中。

The new waveform and protocol can be reprogrammed or configured to achieve different applications. In this paper, a reconfigurable digital signal processing system is designed based on the hardware technology level and digital signal processing technology. This system uses an open VPX architecture to form the platform. The core of this platform is the medium frequency signal processing module.
