Abstract :
A new spreading sequences phase tracking method utilizing the Lorenz dynamic chaotic synchronization is proposed. It has good performance in withstanding the dynamic Gaussian noise existing in the mobile channel distinctly, and shows lower variance characteristics than “early-late” gate PLL circuit. It also gives attractive advice to the simplification of mobile equipment and the solutions of other tough questions in CDMA mobile communications
