在自适应滤波器中干扰信号检测算法的研究
A STUDY OF INTERFERENCE DETECTION ALGORITHM IN ADAPTIVE FILTER
-
摘要: 本文针对自适应滤波器性能易受外部干扰的影响,提出了一种基于自适滤波器进行干扰信号检测(AFDI)的算法,它可以提高自适应算法的抗噪声性能。最后对该算法在强干扰环境的性能进行了模拟,结果表明其各方面的性能指标均优于传统结构的自适应滤波器。

Abstract: The paper presents an algorithm for detecting interference in adaptive filter, because interference can deteriorate adaptive filter performance. The algorithm can improve the performance of adaptive filter under interference environment. The computer simulating results are given in this paper. -
