Lab Director (or Principal Investigator)

Dr. Woon-Seng Gan received his BEng (1st Class Hons) and PhD degrees, both in Electrical and Electronic Engineering from the University of Strathclyde, UK in 1989 and 1993 respectively. He joined the School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore, as a Lecturer and Senior Lecturer in 1993 and 1998 respectively. In 1999, he was promoted to Associate Professor. From 2008-2011, he was the Deputy Director of the Center for Signal Processing. He is currently the Head of Information Engineering Division, School of Electrical and Electronic Engineering in Nanyang Technological University. His research interests include adaptive signal processing, active noise control, directional sound system, psycho-acoustical signal processing, and real-time embedded systems.
Dr. Gan won the Institute of Engineer Singapore (IES) Prestigious Engineering Achievement Award in 2001 for the work on Audio Beam System. He has published more than 200 international refereed journals and conferences, and has been granted five Singapore and US patents. He has co-authored a book on Digital Signal Processors: Architectures, Implementations, and Applications (Prentice Hall, 2005). This book has since been translated to chinese for adoption by universities in China. He is also the leading author of a new book on Embedded Signal Processing with the Micro Signal Architecture, (Wiley-IEEE, 2007). A book on Subband Adaptive Filtering: Theory and Implementation was also published by John Wiley in August 2009. His has also authored a book chapter in Rick Lyonˇ¦s latest book on Streamlining Digital Signal Processing: A Trick of the Trade Guidebook, 2nd Edition, published by Wiley-IEEE press, 2012.
He is currently a Fellow of the Audio Engineering Society(AES), a Fellow of the Institute of Engineering and Technology(IET), a Senior Member of the IEEE, and a Professional Engineer of Singapore. In 2012, he became the Series Editor of the new SpringerBriefs in Signal Processing. He is also an Associate Technical Editor of the Journal of Audio Engineering Society (JAES); Associate Editor of the IEEE Transaction on Audio, Speech, and Language Processing; Editorial member of the Asia Pacific Signal and Information Processing Association (APSIPA) Transactions on Signal and Information Processing; and Associate Editor of the EURASIP Journal on Audio, Speech and Music Processing. He is currently a technical committee member of the Design and Implementation of Signal Processing Systems (DiSPS), and the Industry DSP Technology (IDSP) standing committee of the IEEE Signal Processing Society.

Lab Introduction

The Digital Signal Processing (DSP) Lab at NTU was set up in 1998 after Texas Instruments(TI) awarded the title of Texas Instruments DSP Elite Lab status to NTU. It is also the only TI DSP Elite Lab in Singapore. The role of the TI DSP Elite Lab is to train engineers and researchers in the advanced area of real-time DSP implementation using the Texas Instruments state-of-the-art DSP processors. We have since trained more than 500 students since the inception of the Elite Lab and looking forwards to work closely with TI and other companies in training future manpower in embedded media processing.

Another mission of the DSP Lab is to research into advanced digital audio processing algorithms and applications. We have been working on several new digital audio technologies, such as:
(i) 3D spatial audio processing algorithms for headphones and loudspeakers;
(ii) psychoacoustics low-frequency enhancement algorithms for consumer loudspeakers;
(iii) research into new pre-processing techniques, beamsteering, and spatial sound reproduction for a new-type of directional loudspeakers, known as parametric loudspeakers; and
(iv) sound and noise control techniques that can be applied to confined signal sources and global sound field.

Over the past few years, we have been working with several commercial companies to bring our research results and findings to commercial installations, products, and applications. We have received and delivered several research contracts from companies like Daimler Chrysler (Germany), Singapore Technologies Kinetics, Texas Instruments (USA), Analog Devices (USA), Panasonics (Japan) Excelpoint System, Philips Electronics, and many other local companies. We have also been widely consulted in areas related to real-time DSP implementation and applications, audio and acoustics signal processing, and DSP programming. Furthermore, we also received research grants from several funding agencies, like ASTAR, NRF, and MoE in Singapore to further our basic research activities.
