An ultra-wideband (UWB) pulse design approach for multiple narrowband interference suppression was presented. The generated UWB pulse not only has a very short time duration, but can entirely meet federal communications commission (FCC) spectral mask and effectively suppress the interferences between UWB systems and multiple narrowband communication systems. The coexistence problem between UWB systems and the existing narrowband systems was successfully solved after that. In this approach, the power spectra...
