Approximating Chaotic Time Series through Unstable Periodic Orbits
نویسنده
چکیده
There are many noise reduction methods for chaotic signals, but most only work over a limited signal to noise range. If chaotic signals are to be used for communications, noise reduction techniques which can handle larger amounts of noise (or deterministic noise) are needed. I describe here a method of approximating a chaotic signal by constructing possible sequences based on unstable periodic orbits. The approximation is good enough to distinguish between chaotic attractors, even when large amounts of noise are added to the chaotic signal.

Detecting unstable periodic orbits from transient chaotic time series
We address the detection of unstable periodic orbits from experimentally measured transient chaotic time series. In particular, we examine recurrence times of trajectories in the vector space reconstructed from an ensemble of such time series. Numerical experiments demonstrate that this strategy can yield periodic orbits of low periods even when noise is present. We analyze the probability of f...
متن کاملAnalyses of transient chaotic time series.
We address the calculation of correlation dimension, the estimation of Lyapunov exponents, and the detection of unstable periodic orbits, from transient chaotic time series. Theoretical arguments and numerical experiments show that the Grassberger-Procaccia algorithm can be used to estimate the dimension of an underlying chaotic saddle from an ensemble of chaotic transients. We also demonstrate...
متن کاملDetecting unstable periodic orbits in high-dimensional chaotic systems from time series: reconstruction meeting with adaptation.
Detecting unstable periodic orbits (UPOs) in chaotic systems based solely on time series is a fundamental but extremely challenging problem in nonlinear dynamics. Previous approaches were applicable but mostly for low-dimensional chaotic systems. We develop a framework, integrating approximation theory of neural networks and adaptive synchronization, to address the problem of time-series-based ...
متن کاملUnstable Periodic Orbit Analysis of Histograms of Chaotic Time Series
Using the Lorenz equations, we have investigated whether unstable periodic orbits (UPOs) associated with a strange attractor may predict the occurrence of the robust sharp peaks in histograms of some experimental chaotic time series. Histograms with sharp peaks occur for the Lorenz parameter value r = 60.0 but not for r = 28.0, and the sharp peaks for r = 60.0 do not correspond to any single hi...
متن کاملFinding and Characterizing Unstable Fixed Points by Controlling System Dynamics
We study time series data in order to understand better the underlying dynamics of a system. Unfortunately, many time series do not contain the information we seek in an accessible form, particularly in biological systems which habitually change during the course of an experiment. By using techniques originally developed for controlling chaotic systems, one can enhance the information contained...
