摘　　要：研究超宽带无线通信系统的超短脉冲波形的设计问题,基于FCC频谱约束条件给出超宽带脉冲波形的优化设计方法。提出通过不同高斯波形的适当叠加方法给出简单而性质良好的脉冲波形,其次基于滤波思想给出性态灵活的脉冲波形设计方法。实验表明,本方法十分有效。The problem of designing pulse waveforms for UWB communications was investigated. A method of constructing pulse waveforms was proposed by optimally combining different Gaussian functions, and a simple pulse waveform with some desired properties was constructed by the method. Based on the ideal of filtering, a new approach to designing more flexible pulse waveforms for UWB communications was presented. Several numerical experiments were given to demonstrate the efficiency of this method.
