超寬帶（UWB）技術(shù)在無線通信領(lǐng)域有巨大的應(yīng)用潛力，廣泛實現(xiàn)UWB 的前提是解決UWB 與其它相對窄帶無線系統(tǒng)之間的兼容性問題。本文對這個領(lǐng)域近年來的研究作了綜合評述，介紹了在此方向研究的主要國際機構(gòu)和最新進(jìn)展，對解決UWB 和其它系統(tǒng)共存的方法進(jìn)行了比較和分析。

Abstract: UWB techniques have great advantages in the wireless communication applications. The prerequisite to utilize and proliferate UWB is calling for the consideration on its compatibility with those comparatively narrowband system. This paper reviews the research focused on this area, introduces the main organizations and latest findings. Methods to solve the coexistence between UWB and other systems sharing the same frequency band are compared and analyzed.
Key word: UWB，narrowband systems, coexistence，interference mitigation
