Lyapunov指数在弱2FSK信号检测中的应用
Application of Lyapunov exponent in 2FSK signal chaotic oscillator detection
摘要
Abstract
Concerning the low accuracy and efficiency of the judgment for threshold value and chaos system phase diagram states used in 2FSK signal detection based on Duffing oscillator, the paper adopts the Lyapunov exponents to set threshold value and quantitatively judge states of the Duffing chaos detection system. On the basis of the Lyapunov exponent algo-rithm analysis in Duffing system, the system simulation is carried out. The results show that the FSK signal detection method based on Lyapunov exponent enhances the threshold precision, guarantees the reliability of FSK signal detection.关键词
