| Abstract: | A novel design method for ultra-wideband pulse was presented based on numerical approximation theory.With Chebyshev best uniform approximation rule,the ultra-wideband signal was conformed to FCC spectral mask,which could reduce the interference with other wireless systems and improve the performance of UWB communication system.Comparing with other methods,it is easy to control design precision,and uses spectrum more sufficiently.It is also applicable to different spectral mask.After theoretical analysis,the... |
