摘要 瞬态信号由于短时性、宽频带和相关性强之特点，实际的检测往往比较困难。本文是在LMS算法的基础上，以逐级消除平均误差为准则，对算法进行修正，并根据权向量的收敛过程和权向量误差的有关分析理论基础上，提出了反向滤波的方法。实验表明该滤波算法能有效地提高精度，反向滤波方法能有效地克服了正向滤波权向量不收敛现象。 Because of the shore-time lasting. wideband and strong correlation, it is difficult to detect transientsignal, In this paper, we modify the LMS algorithm with the criterion of gradual eliminating error On the basisof analysing the convergence of weight vector and the error of weight vector, give out reverse filter algorithm. Experiment results show that this algorithm can effectively enhance the accuracy and remove the non convergenceof filter.
