| 摘 要： | 以通用的窄带接收机结构为基础,分析了采用脉冲幅度调制(PAM)的时跳超宽带(TH-UWB)信号对窄带系统的干扰问题,推导出了计算干扰功率的一般闭合公式.分析闭合公式,得到超宽带信号的基本参数对干扰功率的影响.在超宽带脉冲和信号平均功率固定时,给出了降低超宽带信号干扰功率的信号设计方案.通过仿真实验证明了计算公式的精确性和信号设计方案的适用性.

| Abstract: | Based on the structure of normal narrow-band receiver, the interference power of time-hopping ultra-wideband (TH-UWB) signal with pulse amplitude modulation (PAM) on narrowband system was analyzed, and its closed form formula under some practical assumptions was derived. With the UWB pulse and the average power of UWB signal fixed, some design guides were presented to reduce the UWB interference power. Simulations demonstrate the accuracy of the formula and the applicability of the design guides. |
