【摘要】：論文基于“第一代衛(wèi)星移動通信系統(tǒng)信關(guān)站與測試驗證系統(tǒng)關(guān)鍵技術(shù)研究”課題,是衛(wèi)星移動通信終端物理層測試系統(tǒng)研發(fā)工作的一部分。整個測試系統(tǒng)基于Linux操作系統(tǒng)與FPGA平臺構(gòu)成的軟件無線電架構(gòu),以Python和C為主要開發(fā)語言實現(xiàn)了物理層協(xié)議一致性測試的功能,測試系統(tǒng)能夠在本地腳本測試模式和聯(lián)合協(xié)議棧測試模式之間切換以滿足不同的測試需求。論文在研究了整個測試系統(tǒng)的軟件架構(gòu)以及各個模塊功能的基礎(chǔ)上,基于Python開發(fā)語言,實現(xiàn)了物理層業(yè)務(wù)信道的數(shù)字基帶信號處理流程,設(shè)計并實現(xiàn)了物理層與高層協(xié)議間的適配層。在該測試系統(tǒng)的研發(fā)過程中,獨自承擔(dān)測試儀與終端的聯(lián)合調(diào)試工作。目前,通過基帶環(huán)回測試和射頻環(huán)回測試,驗證了物理層基帶信號處理流程的正確性;通過協(xié)議棧聯(lián)調(diào)模式,實現(xiàn)了基于數(shù)字基帶通路的終端入網(wǎng)流程及雙向語音通話功能。
[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.
