Flicker Noise Simulation by Superposition of Normal Stationary Processes

Abstract

The details of the well-known method for representing 1/f noise by a sum of stationary processes are presented. Two series of shaping filters are applied in the frequency band specified by the user. The relations for the filter parameters are determined. The error in the approximation of the spectrum is considered. An algorithm for modeling fluctuations in the form of a system of first-order stochastic difference equations is proposed. The algorithm is intended to be used in simulation models applied to study the errors of navigation systems.
