Abstract: Using the combination of Gaussian monocycles pulse with different amplitude and different delay，a new ultra-wideband（UWB） pulse design method for Inband（either narrowband or wideband） Interference suppression is presented.With a short duration and a simple implement，the obtained UWB pulse can meet Federal Communications Commission（FCC） spectral mask.The theory of the method is explained firstly，then through the examples and simulations，the detail pulse shape and its power spectral density（PSD） are given that satisfy the FCC mask.In the end，the communication performance of the UWB pulse is analyzed in the paper.Comparing with optimal Gaussian-based monocycle，the pulse has an obvious advantage over the optimal Gaussian-based monocycle on Bits Error Rate.
