摘要
根据美国联邦电信委员会(FCC)对超宽带(UWB)信号功率谱分布的规定,论述了作为UWB通信信息载体的脉冲波形对UWB信号功率谱分布的重要性,推导出在脉冲位置调制(PPM)方式下,高斯脉冲及其导函数与UWB信号功率谱中心频率之间的关系.
According to the regulations of the UWB power spectrum distribution by the Federal Communications Commission （FCC）, USA, this paper studies the important influence of pulse waveforms, the carrier of information in UWB communication systems, on the UWB signal power spectral distribution and derives a relation between Gaussian monocycle pulse and its derivatives and the central frequency in the UWB signal power spectrum with pulse-position modulation（PPM）.
