摘　　要：提出了产生避免与WLAN同频干扰的UWB正交成形脉冲序列方法,并到了期望的正交成形脉冲序列.仿真结果表明,利用这种方法产生的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,可以提高系统的发射功率.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.
