| Abstract: | Present a new Ultra-wideband(UWB) pulse design method based on Parks-McClellan algorithm,which renders the pulse design problem equivalent to a Chebyshev function approximation problem.The method is simple and flexible to meet varied request.Simulation illuminate that the resulting pulses not only meet the power spectral constraint of Federal Communications Commission(FCC) UWB mask but also optimally exploit the allowable bandwidth and power. |

| Keywords: | ultra wideband pulse design Parks-McClellan algorithm |
