摘　　要：软件无线电为实现多种无线通信标准提供了方便,其基本思想是构造一个通用的硬件平台,把尽可能多的通信功能用可升级、可替换的软件来实现。采用FPGA+DSP的处理结构,结合高性能的DDC和DUC处理芯片,设计了一个通用软件无线电平台。FPGA能够根据需要完全重新配置,实现特定标准的数据通道,DSP处理器则完成基带处理的算法实现,以实现从一种标准切换至另一种标准。通过测试,系统具有很好的稳定性,信噪比满足通信要求,D/A输出效果好,该系统已作为产品成功地应用于某院校的电子对抗项目。Software radio provides a convenience for realizing a variety of communication standards,its basic idea is to construct a general hardware platform which can achieve the communication function as much as possible by the use of scalable and replaceable software. A general software radio platform is designed which adopts FPGA＋ DSP structure and uses high quality DDC and DUC chips. In the system,FPGA can realize specific standard data channel,and DSP processor can complete the switch of communication standard. The experiment results demonstrate that the system has good stability, SNR can meet communication requirements,and the output of D/A has a good result. As a product,the system has been successfully applied in the project of electronic countermeasures by some institution.
