摘要
应用一维参数化正交小波滤波器逼近一个双正交小波滤波器,利用文中给出的算法,根据信号采样值用Mallat算法对信号进行快速重构,准确得出原始的信号。通过仿真说明了此算法的可行与有效性。
The purpose of this paper is to provide a new method of signal reconstruction. Firstly,we use one dimensional parameter orthogonal wavelet filter to approach a double orthogonal wavelet filter. Secondly, we use Mallat method to reconstruct the signal by a few value of given signal. Finally, we discribe the practicability and effectiveness of the algorithm through simulation.
