摘要：
A novel adaptive UWB pulse shaping algorithm was 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 a better single-link BER performance in AWGN channel, and stronger anti-jamming abilities 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.
