An Efficient Method for Detecting Chaotic Spread Spectrum Sequences

It is an important problem in chaos theory whether an observed irregular signal is deterministic chaotic or stochastic. The detection of chaotic spread spectrum sequences is the prerequisite of molding. This paper proposed a method to detect chaos spread spectrum sequences; even if short data and noise exist the algorithm can detect effectively. Numerical simulations based on Lorenz system verify the effectiveness of the proposed method.
