摘　　要：为了更好地验证认知无线电(CR)技术,提出了一种基于ARM+DSP的认知无线电终端系统的设计方案。该系统以三星公司的S3C2410为中央控制核心、以Ti公司的DSP6416T为实时数据处理核心,最大限度发挥ARM与DSP各自的优势,实现了认知无线电终端间点对点的数据通信和工作频率智能切换,验证了认知无线电的基本概念和关键技术。In order to better verify cognitive radio （CR） technology, a design method of CR terminal based on ARM and DSP is introduced. For availing the advantage of ARM and DSP, S3C2410, produced by SAMSUNG is used as the central control core of the system, while DSP6416T, produced by Texas Instruments, is used as the real - time data processing core. Point - to - point data communication and intelligent switching frequency are realized, and the basic CR＇ s concepts and key technology are also verified.
