Research Institutes

The Institute of Information System is the original Institute of High-speed Signal Processing and Network Transmission (Signal Detection and Processing Laboratory), whose predecessor is the Radar Teaching and Research Group. The Institute now has 7 professors/researchers, 8 associate professors/associate researchers, and 5 lecturers/assistant researchers.

The Institute is subordinate to the first-level discipline Information and Communication Engineering (national key first-level discipline) and has two second-level disciplines, namely Communication and Information System (national key second-level discipline), Information Network and Complex System. It undertakes the teaching of more than 20 undergraduate courses and graduate courses. The Institute recruits more than 30 doctoral and master students each year. In recent years, it has cultivated a wide range of socialist-minded and professionally competent talents including 2 national outstanding doctoral thesis winners, 1 national outstanding postdoctoral fellow, and 1 national excellent instructor.

The research directions of the Institute include Radar Signal Processing, Information Network and Complex System, Satellite Navigation and Countermeasure, Media Signal Processing and Intelligent Transportation. In recent years, it has undertaken and completed many scientific research and technical research projects from the state, ministries and commissions and enterprises, published a good number of high-quality academic papers, and won dozens of national, provincial and ministerial awards including the first prize of national invention.
