Spread spectrum techniques, mobile communications, digital signal processing, antenna arrays, and system identification.

Professor Ng Tung Sang is an expert in mobile communication technologies, especially in CDMA which uses spread spectrum techniques. He received the B. Sc. (Eng.) degree in Electrical Engineering with honours from The University of Hong Kong in 1972. Immediately after graduation, he accepted BHP Steel International’s offer of a graduate electrical engineer position and started working in Newcastle, Australia in November, 1972. While undertaking the one and half year training program he also completed the Master of Engineering Science degree program at the University of Newcastle. He continued his graduate study and completed the PhD programme with a scholarship from the University of Newcastle in 1976.

He then started his academic career with The University of Wollongong, Australia. From 1977 to 1990, he was a Lecturer, then Senior Lecturer and Reader and in December 1990, he took up the appointment of Professor and Chair of Electronic Engineering at the University of Hong Kong, a position he currently holds. He was Head of Department of Electrical and Electronic Engineering from 2000 to 2003 and Dean of Engineering from 2003 to 2007. He is an elected Council Member of the University of Hong Kong since 2004. He has published an edited book, 5 book chapters, over 250 international journal and conference papers and 6 U.S. patents. He has been an editor for several international journals including the IEEE Transactions on Mobile Computing and the International Journal - Engineering Applications of Artificial Intelligence (Pergamon Press).

Professor Ng has been a visiting professor in a number of U.S. and European universities. He is currently holding Honorary/Visiting Professorial appointments in several P.R.C. universities. He is a Chartered Engineer in Hong Kong and a Chartered Engineer in The United Kingdom. He is a Fellow of Hong Kong Institution of Engineers, a Fellow of The Institution of Engineers U.K. (IEE) and a Fellow of The Institute of Electrical and Electronic Engineers, U.S.A. (IEEE).

Professor Ng is very active in international professional engineering activities and has served the IEE and IEEE in various capacities. He was the Vice President of Region 10, IEEE Circuits and Systems Society in 1999 and 2000; a member of the IEE President’s Strategic Working Party on future governance and developments; a member of the IEE Informatics Divisional Board and Executive Committee and an Ordinary Member of IEE Council. He is currently the vice-chairman of The HKIE Accreditation Board.

He was awarded the Honorary Doctor of Engineering Degree by the University of Newcastle, Australia in August, 1997 for his services in Hong Kong to higher education generally and to engineering education specifically. He was awarded the Senior Croucher Foundation Fellowship in 1999, the IEEE Millenium Medal in February, 2000 and the Outstanding Researcher Award by The University of Hong Kong in 2003.
