本文提出一类新的超稳定自适应递归滤波算法。新算法进行参数迭代时取信号的符号而不是象传统算法那样取信号的幅度。因此,算法的计算量大大减少。
In this paper, a new class of adaptive stable recursive filtering algorithm is proposed. The new algorithm takes the sign of the signal instead of the amplitude of the signal as the traditional one. Therefore, the amount of computation of the algorithm is greatly reduced.
