Interplanetary Satellite Link Burst Synchronization Transceiver System Based On

With the continuous development of the current domestic and international ISL technology, it is put forward higher requirements. ISL fast synchronization technology is an indispensable part of the technology, which uses a parallel phase acquisition and DLL tracking loop manner to complete PN code acquisition and tracking. Due to the parallel reasons, it largely shortens the capture time and provides a convenient link for interplanetary satellite technology.The paper focuses on the realization of interplanetary satellite link transceiver based on the synchronization technology. The synchronization theory and synchronization technology in interstellar link are introduced in this paper, and then we presents specific methods of acquisition and tracking technology. The entire project is composed of the IF and RF, which belong to an overall system. This thesis focuses on the IF part, which is totally realized by FPGA. FPGA chip chooses XC4VSX55, the entire design is designed by Verilog HDL language and simulated by modelsim, then the program is downloaded to the FPGA chip after simulation. When the hardware is connected correctly, we use a signal Chipscope to view the testing results which is needed to verify the correctness of the design.This paper is based on a project, and it is completed within the process of the project.
