Decorrelating scaling functions for wavelet transformations
L. V. Novikov · Journal of Communications Technology and Electronics · 2006
A method for synthesizing a mask for a scaling equation with allowance for an a priori given correlation function of the noise component is developed. Two biorthogonal basis functions are generated, with a rational mask contained in one of them. Practical algorithms for calculating the mask coefficients are constructed using the modifications of the known orthogonal scaling functions. The results are confirmed by the examples for two types of correlation functions: an exponential function and its B -spline approximation.
