摘要:提出了产生UWB正交成形脉冲序列且能消除窄带同频干扰的新方法.仿真结果表明:该方法产生的UWB瞬时成形脉冲的功率谱密度分布符合FCC频谱规定的要求,具有很高的频谱利用率,既可以降低用户间干扰,又解决了UWB与窄带系统同频干扰的问题.

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
