【摘要】：论文基于“第一代卫星移动通信系统信关站与测试验证系统关键技术研究”课题,是卫星移动通信终端物理层测试系统研发工作的一部分。整个测试系统基于Linux操作系统与FPGA平台构成的软件无线电架构,以Python和C为主要开发语言实现了物理层协议一致性测试的功能,测试系统能够在本地脚本测试模式和联合协议栈测试模式之间切换以满足不同的测试需求。论文在研究了整个测试系统的软件架构以及各个模块功能的基础上,基于Python开发语言,实现了物理层业务信道的数字基带信号处理流程,设计并实现了物理层与高层协议间的适配层。在该测试系统的研发过程中,独自承担测试仪与终端的联合调试工作。目前,通过基带环回测试和射频环回测试,验证了物理层基带信号处理流程的正确性;通过协议栈联调模式,实现了基于数字基带通路的终端入网流程及双向语音通话功能。
[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.
