Abstract: A new method to generate orthogonal UWB shape pulses is proposed,which has no narrow band interference,and the desired shape pulses have been given.The simulation results show that the power spectral density distribution of the short time impulses that is generated with this method is met to the constraint of FCC spectral mask of UWB and have very high spectral utility rate.This is not only to reduce the interference of multi-users,but also avoid the frequency coexistence interference of UWB and narrow band system.

Key words: UWB (Ultra Wide-Band), shape impulse, PSD(Power Spectral Density), frequency coexistence interference
