NOISE REDUCTION FOR CHAOTIC SIGNALS BASED ON NEW APPROACH OF MEASURING THE SIGNAL DETERMINACY

摘要

Noise reduction for noisy chaotic signals in real world situations is a challenging problem due to the lack of an effective way to measure the noise reduction performance. In this paper a new method for measuring the determinacy of chaotic signals based on the local correlation property of the chaotic dynamic system. The proposed method can be used to yield an improved local-projection algorithm. Numerical results are provided to show the efficiency of the new method.
