Abstract :
A method on detecting unpredictability of chaotic signal is put forward, which is based on periodic orbit statistics. Chaotic time sequences come from analog circuit and numerical simulation respectively. Hot saddle periodic orbits (SPO) are found and its regression spectrum and regression frequency are investigated. The results show that the method is fit for detecting the unpredictability of chaotic system.
