摘　　要：本文基于美国联邦通讯委员会FCC对UWB信号的发射功率谱强制规定,提出了一种新的UWB脉冲成形方法—Gaussian-sinc函数波形脉冲。该方法通过方便灵活的参数调整,可以产生完全符合FCC频谱模板要求的极窄脉冲波形。仿真结果表明,该方法产生的UWB系统发射脉冲旁瓣小,频谱利用率高,不需降低整个频段的信号发射功率,就能有效解决共存通信环境下的同频干扰问题。Based on the FCC（federal communication commission）mask, a novel method to generate ultrawideband shaping pulses, Gaussian-sinc waveforms pulse was proposed. This new approach uses flexible and easy parameters modifications to get narrow pulse waveforms, which comply with the requirement of the FCC special spectrum mask very well. Simulation results show that the UWB pulse is accorded with the FCC mask very well, has lower side-lobe and very high spectrum utilization ratio, and is efficient in co-channel interference mitigation between UWB and other potential communication systems without reduction of the signal transmit power over the whole UWB frequency band.
