Description: Adaptive filter banks as a result of the frequency response to match the statistical properties of the signal, it can be more effective decomposition of the signal. According to the statistical properties of signals, in accordance with the low-pass sub-band energy to maximize the principle of the design of adaptive filters. combination of adaptive filter and the traditional threshold methods, to be a more effective de-noising method. The experimental results show that the standard with the same filter length, the new methods to improve signal to noise ratio greater.
