Continuous Simulation of Gaussian Processes with Given Spectrum

Part of: Structural Safety and Reliability
Abstract:
A new algorithm, to be called MIMA (modulated interpolated moving average) allows stationary Gaussian processes with given spectral density to be simulated in continuous time, while providing a close upper bound for the error committed. Derivation of the algorithm relies on both the frequency domain and the time domain approaches. It is particularly suitable for narrow-band processes. Two numerical applications are given, the second being the W.J. Pierson-L. Moskowitz spectrum for fully developed wind sea heights.
