Signal coding and compression based on chaos control techniques

This paper presents a new technique for signal coding and compression based on chaos control techniques. Given signal (e.g. speech or any other) recorded in a time interval is cut into smaller samples, further each of the sections is stored as a piece of a chaotic trajectory supplied by a chosen chaos generator (coder!). Effective techniques (based on a chaos control procedure) for finding initial conditions of the chaos generator to produce a desired shape of the output signal with a desired accuracy are described. In effect the signal to be coded/compressed can be stored as a set of points-initial conditions of the chosen chaos generator. Recovery of the original signal is straightforward: the stored initial conditions are applied to the coding chaos generator and the solutions taken in appropriate intervals are simply pieced together. Advantages and drawbacks of the proposed technique are discussed
