摘　　要：针对基于脉位调制的跳时宽带信号与其带宽内其他窄带系统存在相互干扰的问题,提出在期望的频段上形成凹口的跳时序列构造方法,并描述该方法的具体步骤。仿真实验结果表明,该方法通过构造合适的跳时序列,能在一定程度上控制功率谱密度的分布,达到共享频带的目的。Aiming at the question that mutual interference exists between time-hopping wideband signal based on pulse position modulation and other systems occupying the same band,several code construction methods that allow to place a notch or a zero in a expected frequency are introduced.The specific steps are given.Simulation results prove that spectrum can be controlled by time-hopping sequence to some extent.
