| 摘 要： | 提出一种抑制UWB发射信号离散功率谱线的方法,通过在发射的脉冲中加入随机相位,可以使UWB信号的功率谱变得平滑从而提高系统的功率利用率.与传统基于跳时调制的功率谱平滑方法相比,该方法具有更好的平滑效果和更低的实现复杂度.理论分析和计算机仿真结果验证了所提方法的有效性.

| Abstract: | In this paper,an approach by giving the transmitted pulse a random phase jitter is presented to eliminate the discrete power spectrum density(PSD) components of UWB siagnal,it can smooth PSD of the impulse ultra-wideband(IR-UWB) signal with better performance and relatively low system complexity when compare with traditional time-hopping scheme.Theoretical analysis and simulation results demonstrate the validity of the proposed method. |
