Main Achievements

1.Effective Image Compression and Video Coding System

We have developed a high-performance image compression system, which was successfully used in Chinese Space Programs, such as Chang'e I spacecraft,Chang'e II spacecraft, Shenzhou VII spacecraft, Tiangong I spacecraft, and so on.The Chang'e II lunar probe has achieved a full-size moon image with a 7-meter resolution of 100% coverage, the highest one ever issued in the world. This achievement has been honored with National Prize for Progress in Science andTechnology.

2. Cognitive Wireless Ad Hoc Network

We have advanced the theory and technology of high dynamic cognitive ad hoc networks, which breaks through the technique bottleneck of large-scale development.We have also made significant innovations in spectrum detection, key node determination and fuzzy mixed adaptive routing protocol, which has reached the international level. The research has won the first Provincial Prize in Scienceand Technology.

3. Shannon Information Theory and Related Advancement

We have presented the theory of secure network coding, and proposed a method for constructing a family of asymptotically good quantum codes based on concatenation structures. We have also constructed resilient Boolean functions with near optimal nonlinearity, which was further developed into the well-known Xiao-Massey theorem. The related research results have been published in some important international journals, including Proceedings of the IEEE, IEEE Journalon Selected Areas in Communications, IEEE Transactions on Information Theory,and so on.

4. Efficient Wideb and Wireless Transmission System

We have proposed the construction and decoding methods for the low-complexity multi-element LDPC code and have firstly designed the related encoder and decoder on GF(64). We have also developed optimized methods for combining channel code and network code, and novel cooperated transmission protocols. We have published our research results in some important journals, for instance,IEEE Transactions on Information Theory, etc.

5. Information Network Security Theory and Technology

We have developed the Wireless Authentication and Privacy Infrastructure (WAPI)for wireless information network security. As an influential national standard,WAPI has been adopted by more than 100 domestic and overseas manufacturers.WAPI has successfully broken the international technique monopolization and was honored with National Award for Technological Invention. We have also proposed the Triple-Element and Peer-to-Peer Authentication (TePA) for access control.TePA has been approved as an international standard by ISO/IEC, which was one of the top 10 technique events of national communication industry in 2010. The core patent of TePA has won the Golden Patent Award in China.
