| Abstract: | A method of the fractal signal processing in the orthogonal wavelet is applied to the B spline wavelet and biorthogonal wavelet. The author estimates the 1/f type fractal signal embedded in additional white Gaussian noise. The computer simulation testifies its effectiveness and viability . |
