摘要 分析了认知无线电技术与超宽带技术相结合的必要性及可行性,阐述了认知超宽带(CUWB)无线通信系统的基本工作原理,描述其认知过程,给出系统认知循环的处理模型,并在此基础上设计出了系统的结构框架,最后对CUWB系统的若干关键技术进行了探讨. In this paper, essentiality and feasibility of the research combined ultra wideband with cognitive radio were analyzed. Then, the paper expounded the operating fundament of cognitive ultra wideband （CUWB） wireless communication system, described the system cognitive cycle, gave a simple system cognitive cycle processing model, and established the framework of CUWB system based on cognitive model. Finally, the issues of some key techniques of CUWB system were analyzed.
