摘要

本文利用小波包的正交性和各频率频率分辨率任意的动机,研究了一种新的基于小波包的自适应算法。在此基础上,研究了基于自适应算法的有源镇定降噪问题。通过数值仿真验证了该方法的有效性。

Adaptive Filter Algorithm Based on Wavelet Packets and Application to Adaptive Active Noise Cancellation
In this paper, on the motivation of arbitrariness of frequency resolution at all frequencies and property of orthogonalization of wavelet packets, we investigate new adaptive algorithms based on wavelet packets. Moreover, the active noise cancellation with stabilization is investigated by using the presented adaptive algorithm. The effectiveness is demonstrated through numerical simulation.
