认知UWB无线通信系统研究展望
首发时间:2006-08-03
摘要:阐述了将认知无线电(Cognitive Radio, CR)技术与超宽带技术相结合进行研究的必要性及可行性,并在此基础上给出了研究基于CR思想的UWB系统的基本理论与关键技术。认知超宽带(CUWB)无线通信系统是将CR和UWB技术优点相结合,能针对功率、距离和所要求的数据率进行频谱优化,更好地解决了UWB系统的频谱共享灵活性及系统共存性问题。

prospect of research: cognitive ultra wideband wireless communication system
Abstract:In this papaer, essentiality and feasibility of the research combined cognitive radio with ultra wideband was analysised. The issues of key techniques were discussed. Cognitive ultra wideband(CUWB) wireless communication system had characteristics and merits of both cognitive radio and UWB. CUWB can perform spectrum optimizing for power, distance and desired data rate in order to preferably resolve the problems of spectrum sharing facility and system coexist of UWB.
Keywords: CR, UWB, spectrum sensing, adaptive pulse waveform shaping, CUWB
