Estimating a Nonparametric Colored-Noise Model for Linear Slowly Time-Varying Systems Vrije Universiteit Brussel
This paper proposes a methodology to easily extract some valuable nonparametric information on linear slowly timevarying systems, which have been excited by multisines. More specifically, it is first explained how time-varying systems behave when excited by multisines and how a rough nonparametric idea of the speed of variation of the instantaneous frequency response function is estimated. Second, a nonparametric model of the disturbing colored ...
