Design and Implementation of Digital Intelligent Carrier Synchronization Loop

摘要：

In order to demodulate data correctly in satellite positioning system under high dynamic circumstances, the reliable code tracking and carrier tracking are necessary after code acquisition. In order to overcome the carrier Doppler frequency shift in notable high dynamic applications, the fuzzy logic controller is introduced in the carrier tracking loop in this paper. So the intelligent filter which is made up of fuzzy logic controller and loop filter can dynamically verify loop bandwidth. Then the simulation results show that the proposed intelligent filter can work better than the existing design.
