Abstract
Cognitive Ultra Wideband Radio is proposed to exploit the advantages of combining Cognitive Radio with Ultra Wideband technologies, so as to solve the problems of coexistence and compatibility between UWB and other existing narrowband wireless systems. A novel adaptive UWB pulse shaping algorithm with low complexity, instead of notch filter, is presented for producing the expected spectral notches right in the frequency band occupied by the nearby wireless devices. Simulation results show that the proposed UWB waveform has better single-link BER performances in AWGN channel and stronger anti-jamming ability than other conventional waveforms such as Scholtz's monocycle, etc. Besides, the power spectral density of UWB pulse does not need to be reduced over the whole frequency band. Therefore, it is possible to expand the communication range of UWB systems by increasing the transmitted power of UWB pulse.
