| 摘 要： | 针对转发式干扰机发射的干扰信号通过空间耦合对接收机造成的影响，提出了基于LMS算法的自适应对消结构，并针对宽带信号，对结构作出了调整。重点是利用可变分数延时滤波器来实现参考信号与干扰信号时间的对齐，从而达到宽带对消的效果。提出了能够实现可变分数延时滤波器的结构。通过仿真表明该对消结构能够很好地对消宽带干扰。

| Abstract: | In view of the effects of the interference signals transmitted by the repeater jammer through the spatial coupling on the receivers,the adaptive cancellation structure based on the LMS algorithm is presented,and adjusted for the wideband signals with an emphasis on making the reference and interference signals aligned through the variable fractional delay filter,thus achieving the effects of the wideband cancellation.In addition,a structure that can realize the variable fractional delay filter is proposed.F... |
