摘要：

Cognitive Ultra Wideband (UWB) Radio is proposed to exploit the advantages of combining Cognitive Radio with Ultra Wideband technologies. In order to realize Cognitive UWB Radio, nuiltiple pulse waveform adaptations have been investigated for producing the expected spectral notches while matching with FCC spectral mask and other frequency regulation requirements. To verify the pulse distortion effect of UWB antenna on Cognitive UWB Radio, the generated pulse waveform is further transferred through an actual UWB antenna. Furthermore, pre-equalization scheme is considered before antenna transmission, so as to compensate the pulse distortion effects.
