| 摘 要： | 介绍了一种新颖的频域陷波算法,以消除窄带干扰对通信的影响,并讨论了这种陷波算法在直接序列扩频通信中的应用。该算法将时域自适应滤波器中复杂的卷积运算转换为频域的相乘运算,从而减少了运算量,节省了资源,使得自适应陷波器更易于工程实现。仿真结果证实,该算法能有效地消除直接序列扩频方式中的窄带干扰。

| Abstract: | A novel notch filter algorithm is present to eliminate the interference of narrowband noise in di- rect sequence spread spectrum communication.This algorithm converts the complex convolution algorithm in time domain into the simple multiplication in the frequency domain,so the operation is simplified and the im- plementation is easier.The simulation results show that the algorithm can effectively eliminate the interference of narrowband noise in direct sequence spread spectrum. |
