چکیده

Abstract We investigate the stochastic behavior of single-trajectory spectral density S ( ? , T stretchy="false">) several Gaussian processes, i.e., Brownian motion, Ornstein–Uhlenbeck process, gyrator model and fractional as a function frequency ? observation time $\mathcal{T}$?> . evaluate in particular variance frequency–frequency correlation for different values show that these properties exhibit behaviors physical cases can therefore be used sensitive probe discriminating between kinds random motion. These results may prove quite useful analysis experimental numerical data.

Persistence of Gaussian processes: non-summable correlations

Suppose the auto-correlations of real-valued, centered Gaussian process Z(·) are non-negative and decay as ρ(|s − t |) for some ρ(·) regularly varying at infinity of order −α ∈ [−1, 0). With Iρ(t) = ∫ t 0 ρ(s)ds its primitive, we show that the persistence probabilities decay rate of − logP(supt∈[0,T ]{Z(t)} < 0) is precisely of order (T/Iρ(T )) log Iρ(T ), thereby closing the gap between the lo...

The Rate of Entropy for Gaussian Processes

In this paper, we show that in order to obtain the Tsallis entropy rate for stochastic processes, we can use the limit of conditional entropy, as it was done for the case of Shannon and Renyi entropy rates. Using that we can obtain Tsallis entropy rate for stationary Gaussian processes. Finally, we derive the relation between Renyi, Shannon and Tsallis entropy rates for stationary Gaussian proc...

Convergence of densities of some functionals of Gaussian processes

We study the convergence of densities of a sequence of random variables to a normal density. The random variables considered are nonlinear functionals of a Gaussian process. The tool we are using is the Malliavin calculus, in particular, the integration by parts formula and the Stein’s method. Applications to the convergence of densities of the least square estimator for the drift parameter in ...

Simulation of Gaussian Processes and First Passage Time Densities Evaluation

Motivated by a typical and well-known problem of neurobiological modeling, a parallel algorithm devised to simulate sample paths of stationary normal processes with rational spectral densities is implemented to evaluate first passage time probability densities for time-varying boundaries. After a self-contained outline of the original problem and of the involved computational framework, the res...

Log-spectral magnitude MMSE estimators under super-Gaussian densities

Despite the fact that histograms of speech DFT coefficients are super-Gaussian, not much attention has been paid to develop estimators under these super-Gaussian distributions in combination with perceptual meaningful distortion measures. In this paper we present log-spectral magnitude MMSE estimators under super-Gaussian densities, resulting in an estimator that is perceptually more meaningful...
