In order to make full use of the licensed frequent band, Cognitive Ultra Wideband (CUWB) is proposed, which can take full advantages of Ultra Wideband such as high secrity, low power spectral density, high data rate and the opptinutic spectrum use of cognitive radio.
无线通信技术的迅猛发展使得人们对频谱资源的需求不断增加,但各国采用的固定分配频谱政策使得大量的民用、军方、雷达等都集中在一个频谱范围内,使原本有限的频谱资源显得越发拥挤,与之对比的是对于已授权频段利用率十分低下,为此人们提出了认知超宽带技术,它既可以充分发挥超带宽无线通信技术高保密性、高速率、低功耗等优势,也可以充分利用认知无线电灵活频谱利用方式,有效地解决超宽带和认知无线电各自面临的困境,充分发挥各自的特点,从而提供一个高速有效的通信手段,为解决目前无线电资源困境提供了一个新的解决思路。
