摘　　要：提出了一种基于IIR陷波的UWB窄带干扰抑制方法。超宽带脉冲通过IIR陷波来降低自身特定频段的功率谱从而使UWB系统避开窄带干扰，达到与其它系统共存的目的。以高斯导脉冲为例，对所设计IIR陷波器进行仿真验证，并就陷波前、后的脉冲波形的通信性能进行比较。仿真结果表明：陷波脉冲具有良好的窄带干扰抑制能力，在实现和其他无线窄带通信系统共存的同时，具有良好的系统传输性能。The ultra wide-band （UWB） narrowband interference suppression method based on IIR notch filter is presented. In order to avoid the narrowband system interference, the power spectral density （PSD） of UWB pulses in some frequency band is attenuated by trapped the pulse. The designed IlR notch filter is confirmed by simulating with example of the Gaussian pulse derivatives, and the communication performance of the pulse and the trapped pulse is compared. The simulation results show that the trapped pulse effectively suppresses the narrowband interferences, successfully solves the coexistence problem between UWB system and other existing communication systems and has the good system transmission performance.
