An Efficient Algorithm for Generating Colored Noise Using a Pseudorandom Sequence

Authors: Borish, Jeffrey

Abstract

Filtering white noise to obtain any desired power spectral density can be expedited by starting with a maximal length sequence: its binary nature eliminates multiplications from the convulotion operation, and the number of additions can be reduced to the order of 2.5n log(2)n, where n is the length of the sequence, using an algorithm based upon the fast Hadamard transform.
