Weak GPS Signal Detect Algorithm Based on Duffing Chaos System

摘要：

This paper works on the weak GPS signal detect based on Duffing chaos system. Because the chaos system has good sensitivity to weak signal and strong immunity to the noise, traditional correlation process is combined with chaos system to implement GPS weak signal detect, and Lyapunov exponent of the chaos system is statistically analyzed. It has been improved that this algorithm can efficiently enhance weak signal detect for GPS receiver.
