| Abstract: | Synchronization system is the key of the wireless navigation system, the PN code tracking system is the importance of synchronization. The text researched deeply in full time exeeedlay unconcerned delay PLL system, and set up the math model for it,and diseuss the PN code tracking system through simulation . On this base ,the performance of PN code tracking is tested with the FPGA developing system of Insight corp. |
