Abstract: Abstract Fractional Brownian motion (fBm) offers a convenient modeling for non-stationary stochastic processes with long-term dependencies and 1/f-type spectral behavior over a wide range of frequencies. The orthonormal wavelet transformation coefficients of fBm are analyzed. We introduce the wavelet synthesis algorithm of fBm, and try to improve the algorithm on this basis. A variety of results from simulations are presented to demonstrate the melioration of the algorithm
