Cognitive ultra-wideband (UWB) radio is proposed to exploit the advantages and the unique features of enhancing UWB wireless technologies by utilizing cognitive radio functionality. In order to achieve the cognitive UWB radio, multiple pulse waveforms adaptation has been investigated for producing the expected spectral notches while matching with the Federal Communications Commission (FCC) spectral mask. Then the specifically designed pulse waveform with adaptive spectral notches is tested by high-speed digital processing unit for implementation estimation. To verify the pulse distortion effects of UWB antenna in the cognitive UWB radio, the generalized pulse waveform is further transferred through an actual UWB antenna. Furthermore, a pulse waveform predistortion scheme is considered before antenna transmission, so as to compensate the pulse distortion effects.
