在自適應(yīng)濾波器中干擾信號檢測算法的研究
A STUDY OF INTERFERENCE DETECTION ALGORITHM IN ADAPTIVE FILTER
-
摘要: 本文針對自適應(yīng)濾波器性能易受外部干擾的影響,提出了一種基于自適濾波器進(jìn)行干擾信號檢測(AFDI)的算法,它可以提高自適應(yīng)算法的抗噪聲性能。最后對該算法在強(qiáng)干擾環(huán)境的性能進(jìn)行了模擬,結(jié)果表明其各方面的性能指標(biāo)均優(yōu)于傳統(tǒng)結(jié)構(gòu)的自適應(yīng)濾波器。

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. -
