R&D Progress in Wireless Communications in China - A Review on Chinese High-Tech R&D Programs for Wireless Technology

China has experienced fast growth in mobile communications. Now, China is the world largest mobile communication country with about 500 million users. Wide applications of mobile communications are giving strong pull to the research and development on the broadband wireless communication technology to meet the fast growing demand for high speed access into the information infrastructure. This makes the R&D on wireless technology play great role in the Chinese High-Tech program. This paper will review the key project — FuTURE (Future Technology for Universal Radio Environment) — development of the 863 program, which represents the Chinese efforts towards IMT-advance. Taking some works done in the Tsinghua National Laboratory for Information Science and Technology as examples, the paper will show what has been made in China on the broadband wireless technology, including the trial network in Shanghai. key words: China’s hightech program, wireless communication, distributed cellular system, interleave division multi access, constellation overlapping
