To fully use the ultra wideband (UWB) spectrum energy regulated by FCC, a optimum algorithm for UWB pulse design based on FFT has been proposed in this paper. The frequency expression of UWB signal has been firstly formed by the combination of different basis waveform, and then the UWB pulse can be easily obtained by IDFT on the frequency expression. This designed UWB pulse can achieve a satisfactory match to FCC mask, and the normalized frequency utilization can even reach 94.15% which may be superior to the other UWB transmitted signals.
