【Abstract】 A method to generate orthogonal UWB shape pulses is proposed,which have no co-channel interference with WLAN,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.This can improve the emitting power of UWB system.更多还原
