This paper introduces the operating fundament of Cognitive Ultra WideBand (CUWB) wireless communication system and gives a scheme of dynamically obtaining adaptive emission mask based on spectrum sensing to adapt to spectrum environment and be compatible with FCC spectral mask. Then, a method to generate adaptive CUWB shaping pulse is proposed based on weight combination of Prolate Spheroidal Wave Functions(PSWFs) matching UWB multiple sub-band spectral mask. The simulation results show that the pulse waveforms shaped by this method conform the spectral mask constraint for CUWB, adapt to dynamical variety of the spectral mask.
