[Abstract]:Based on the research of key technologies of the first generation satellite mobile communication system, this paper is a part of the research and development of the physical layer test system of satellite mobile communication terminal. The whole test system is based on the software radio architecture of Linux operating system and FPGA platform. The function of physical layer protocol conformance testing is realized with Python and C as the main development languages. The test system can switch between local script test mode and federated protocol stack test mode to meet different test requirements. Based on the research of the software architecture of the whole test system and the function of each module, this paper realizes the digital baseband signal processing flow of the physical layer service channel based on the Python development language. The adaptation layer between physical layer and high layer protocol is designed and implemented. In the process of research and development of the test system, the joint debugging of the tester and the terminal is undertaken alone. At present, the correctness of baseband signal processing flow in physical layer is verified by baseband loop test and RF loop test, and the terminal access flow based on digital baseband path and bi-directional voice call function are realized by protocol stack coupling mode.
