| 摘 要： | 从频域角度探讨TH-UWB系统对窄带干扰的抑制能力,采用信号功率谱分析方法,研究UWB系统的调制技术和脉冲成形技术,提出线性组合高斯单周脉冲设计陷波频谱.理论分析及计算机仿真结果表明,合理选择超宽带信号调制方式和脉冲,可在一定程度上提高超宽带系统抗干扰能力.应用提出的线性组合高期单周脉冲作为UWB发射信号,可以有效减小UWB信号对外界的干扰.

| Abstract: | The interference of narrowband signal on TH-UWB system is analyzed from the angle of frequency domain,techniques including modulation,pulse and shaping ale studied by means of powers pectral density(PSD).It concludes that the interference can be reduced on some extent by choosing different modulation technology and pulse shape of UWB properly.Mitigation by UWB signals ale put forward first such as linear combination of Gaussian monopulse wavoform. |
