摘要：
We consider quadrature mirror filters, and the associated wavelet packet transform. Let X = {X(n)}(n is an element of Z) be a stationary signal which has a continuous spectral density, f. We prove that the 2(n) signals, obtained from X by n iterations of the transform, ''converge'' to white noises when n --> +infinity. If f is holderian, the convergence rate is exponential.
