Abstract
A method, based on fundamental properties of chaotic dynamics, is devised for filtering in-band noise of an incoming signal generated by a chaotic oscillator. Initially the $2x$ mod 1 map is used to illustrate the procedure and then the method is applied to recover the message encoded in a realistic chaotic signal, after the transmitted signal has been contaminated with noise.

Using simple scaling arguments, it is shown that at large particle number the kinetic energy is a small perturbation, and the spatial structure of the cloud of atoms and its momentum distribution dependent in an essential way on particle interactions is found.

It is shown that the recent realization that chaos can be controlled with small perturbations can be utilized to cause the symbolic dynamics of a chaotic system to track a prescribed symbol sequence, thus allowing us to encode any desired message in the wave form from a chaotic oscillator.

Noise-reduction methods for reducing noise in time-series data whose underlying dynamical behavior can be characterized as low-dimensional chaos should be used more widely, particularly in studies of attractor dimension, Lyapunov exponents, prediction, and control.

It was found that all proposed methods converge in this ideal case, but not equally fast, and it is suggested that these nonlinear noise reduction schemes should be compared to Wiener-type filters.

This paper presents experiments and an approximate analytical model that quantify and explain the observed robustness of synchronization in the Lorenz system, and explains why speech and other narrowband perturbations can be recovered faithfully, even though the synchronization error is comparable in power to the message itself.

It is demonstrated that it is not difficult to choose the parameters of this algorithm, even though it uses no other information about the underlying dynamics than the data themselves, and the noise reduction is very robust with respect to changes in the choice of parameters.
