摘要/Abstract

摘要：

基于压缩Chirp脉冲与信号的线性叠加，提出了一种产生超宽带(UWB)成形脉冲的新方法. 该方法可以灵活方便地得到符合特定频谱要求的成形脉冲，能抑制UWB系统与窄带通信系统之间的同频干扰. 仿真结果表明，产生的UWB瞬时成形脉冲, 其功率谱密度分布符合美国联邦通信委员会(FCC)的要求，而且具有极高的频谱利用率；不需要在整个频段降低发射信号的功率，就可以解决UWB系统与现有窄带通信系统之间的频谱共存问题.

关键词: 超宽带, 成形脉冲, 功率谱密度, 线性调频, 同频干扰

Abstract:

Based on compressed chirp pulses and the linear superposition of these signals, a novel method to generate ultra wide band (UWB) shaping pulses was proposed. It is flexible and easy to get UWB shaping pulses, which not only can comply with the requirement of a special spectrum mask, but also can suppress the co-channel interference between UWB and the existing narrow band systems. The simulation results show that the power spectral density(PSD) distribution of the UWB shaping pulse is accorded with the federal communications commission(FCC) mask very well, and also has very high spectrum utilization ratio. It needn’t to reduce the transmitted power in the whole UWB frequency band to resolve the co-existence problem between UWB and the narrow band communication systems.

Key words: ultra wide band, shaping pulse, power spectral density, linear frequency modulation, co-channel interference
