基于RLS算法的直接序列扩频抗窄带干扰技术

The Techniques of Narrow Band Interference Rejection in DSSS Based on RLS Algorithms

在敌方有意的窄带强干扰下,扩频通信系统可以利用时域自适应滤波算法来抑制干扰。介绍了基于时域预测的自适应滤波RLS算法,仿真结果表明其对DSSS系统中的窄带干扰有较好地抑制效果。

Adaptive filtering algorithms can be used on time domain to rejection Narrowband interference （NBI） of man-made of enemy in DSSS. RLS algorithm based on time domain predict is introduced in this paper. The result of these simulations is proved by the fact that RLS have good effect on the interference suppression to NBI in DSSS.
