Over the years, Xidian University has had Modern Electronic Information and Communications Theories and Technologies as its major academic directions. It has two first-grade disciplines, Information and Communications Engineering and Science of Military Command. With such research bases and platforms as the State Key Laboratory of ISN, Key Laboratory of Computer Network and Information Security of the Ministry of Education, Key Laboratory of Wireless Communications of the Ministry of the Information Industry, National-level Discipline Innovation and Wisdom Absorption Base of Modern Wireless Information Network Fundamental Theories and Technologies, and Innovative Technology Development and Technical Service Platform for Modern Wireless Communications of Shaanxi Province, Xidian University has been active in undertaking projects supported by the National Natural Science Foundation, the 973 Program, the 863 Program, the National Technical Support Program, Major National Science and Technology Programs, pre-researches on National Defense Equipment, researches on equipment models and a large number of international cooperation subjects and projects. With its profound study in the field of Modern Communication and Information Engineering, Xidian University has made great contributions to the development of China’s Communications Technology.
In the period of the Tenth and Eleventh Five-Year Plans and the 211 Project construction, Xidian University has undertaken and accomplished a large number of scientific and technological projects in the fields of the New-generation Wideband Wireless Mobile Communications Network, Next-generation Internet, Network and Information Security, Multimedia Communications, and Military Communications Technology. It has achieved a breakthrough in the theories and key technologies for Highly Mobile Large Scale Wireless Ad hoc Networks, Wireless Cognitive Networks, Wireless Network Resource Management, Wideband Wireless Transmission, Communications Signal Processing, High-efficiency Signal Source and Channel Coding, High Definition Earth Observation, Network Coding, Network Detection and Management, Optical Fiber Wideband Communications Networks, Secure Architecture and Protocol of Wireless Networks, Cryptograph Design and Analysis, Digital Signature and Authentification, Special-purpose Anti-interception Anti-jamming Communication System, Quantum Communications, and Communications Counter-measure. A large number of research results of great social or economic value have been achieved. Since the beginning of the Tenth Five-Year Plan, Xidian University has obtained up to 50 million Dollars’ research fund in these fields, had more than 100 academic monographs and textbooks published, and had 75 patents for inventions. More than 3000 papers have been indexed by SCI and EI.
Xidian University developed China’s first meteor burst communications system, first millimeter wave communications equipment and first ATM switch. The five first-generation meteor burst communications experimental models( from Model HX－101A to Model HX－101E) won the National Science Convention Award in 1978 and the Scientific and Technological Achievement Award (Second Prize) of the Ministry of Electronic Industry in 1983. Since the mid and late 1990s, Xidian University has taken the responsibility for the research, demonstration and verification of the new-generation meteor burst communications system. The research on its key technology is leading China, laying a solid foundation for the development of the equipment model and its large-scale popularization.
Since the beginning of the Tenth Five-year Plan, Xidian University has made outstanding scientific achievements in this field. The projects of Wideband Wireless IP and Wideband Integrated Accessing have gained the nation’s special fund. Some research results have been set as the nation’s industry standard and gained marked social and economic benefit. The major project of China’s High-speed Information Demonstration Network Engineering, undertaken by Xidian University, from the Ministry of Science and Technology has laid a technical foundation for the nation’s new-generation backbone Internet. Xidian University has developed China’s first COFDM based DTV ground broadcast prototype, making great contributions to the standardization and industrialization of China’s digital TV broadcasting; developed China’s first real-time remote sensing image compression system with a compression ratio of 8:1, which was applied successfully to China’s satellite effective load; developed an orthogonal time-division multiplexing based non-renewable on-board switching and processing system, paving a new way for China’s satellite communications mechanism.
Since the beginning of the Eleventh Five-year Plan, Xidian University has undertaken a number of the nation’s special scientific projects. It has submitted some proposals in the field of cognitive wireless communications engineering to such domestic or international standardization organizations as ITU with five of them adopted, and some of the research results have been applied successfully to the industrialization of wireless communications equipment. It has participated in the formulation of the technical scheme of Physical Layer Transmission Mode and Media Access Control Protocol for High-performance Network Over Coax(HINOC); developed China’s first aerospace image compression chip and first wavelet based high-performance satellite carrying image compression system, which was applied successfully to China’s circumlunar satellites Chang’e 1 and Chang’e 2 and Shenzhou Ⅶ with its technical level leading the nation; developed a performance prototype of the quantum switch, establishing a quantum privacy channel and quantum communications network demonstration system with its research result leading the world.
Xidian University has also made remarkable achievements in the field of cryptology and information security. It is the first to propose studying the analysis and design of the flowing cryptograph system by the spectral technology. A theory with sound systems has been established and serves as the basis for a systematic theory of flowing cryptograph stability. It has been the presiding formulator of the standard for Wideband Wireless Network WAPI Security Technology, which broke the European and American monopoly in the wireless LAN security standard and was set as a national standard in 2003. On June 1, 2010, the standard of the WAPI fundamental frame method (or Tiger Tally TePA) is officially released by ISO/IEC(standard number: ISO/IEC 9798-3:1998/Amd.1:2010. This is China’s first international standard approved in the field of fundamental and generic technology of information security, which means China has achieved a breakthrough in the internationalization of the WAPI standard, of which China has independent intellectual property rights. The SSF42 high speed public key encryption algorithm developed by Xidian University has been approved by the State Cryptography Administration and applied to such financial payment systems as China Merchants Bank with economic gains of approximately 7.40 million dollars achieved.
