| 摘 要： | 在分析基于自适应多门限算法的变换域窄带干扰抑制算法的基础上，利用变异系数解决了该算法在信噪比高时干扰抑制性能急剧下降的问题。数字仿真结果表明，应用变异系数后的算法不仅可有效抑制直扩系统中的窄带干扰，且易于工程实现。

| Abstract: | The paper solves its bad performance by introducing coefficient of variation when noise-to-signal is high,based on the analysis of narrow-band interference suppression in transform domain based on adaptive multi-threshold algorithm.Simulation showed that the algorithm has better adaptive performance by introducing coefficient of variation in suppressing narrowband interference in DSSS signal and that it can be carried out in project. |
