%X Considering the various combinations of derivative for modified Hermite functions to get the optimal waveform,the relation between the normalized energy of the n-th derivative of the modified Hermite functions and the pulse shape parameter α as well as the order n of differentiation is studied.A novel method to design ultra-wideband(UWB) pulse is proposed in terms of the spectral mask standard that is set up by Federal Communications Commission(FCC).The optimal waveform is gotten by the linear combination of the N modified Hermite functions.The simulation results indicate that the pulse obtained from this method can approach the spectral mask standard accurately,which makes the transmission power bigger under the condition of FCC.
