频谱测量接收机嵌入式最小系统的设计

以软件无线电无线频谱测量接收机为应用背景,设计了一种基于ADI公司的Blackfin537DSP芯片和操作系统的通用的嵌入式最小系统。提出了一例基于该最小系统的控制器和数字信号处理器的设计方案和具体应用,详细阐述了各关键部分的设计,包括硬件结构和基于的软件结构。实验结果表明,该方案可以充分利用数字信号处理技术,有效地简化系统设计,降低开发成本和开发周期,既能够满足软件无线电频谱测量接收机对控制器和数字信号处理器的要求,也可以作为数字化网络化接收机的通用的音频、视频处理单元和播控系统,在现代广播领域发挥重要作用。

Design and Implementation of an Embedded System in the Radio Spectrum Monitoring Receiver

This paper introduced an all-purpose Embedded System made up of Blackfin537 and OS used in a Radio Spectrum Monitoring Receiver, brought forward a design Project based on this Embedded System which is used as the control center and digital signal processing center, expounded the design of the hardware frame and software frame (based on ) concretely. This plan predigested the design of the system, reduced the cost and the period of development. It can meet the needs of a Radio Spec- trum Monitoring Receiver ...
