Researcher

Biography

I am a researcher with Wireless Signal Processing (WSP) Program, NICTA. Recently I have been working on the InterfereX Project that aims to develop an advanced modem solution for 3G/4G mobile wireless communications. I am also an adjunct research fellow at Research School of Information Sciences and Engineering (RSISE), Australian National University (ANU). Prior to this, I worked as a post-doctoral fellow at University of Utah, UT.

My research interests include: 
•    Turbo principle and its applications in receiver design.
•    Multiuser detection theory in multiple-access channels.
•    Synchronization, channel estimation and equalization in time-frequency dispersive channels.
•    Monte-Carlo Markov-Chain techniques in signal detection and parameter estimation.
•    Code-division multiple-access (CDMA) and interleave-division multiple-access (IDMA).
•    Multiple-input multiple-output (MIMO) systems.
•    Orthogonal-frequency division-multiplex (OFDM), MIMO-OFDM and OFDMA systems.

Education

•    Ph.D., Electrical and Computer Engineering, University of Utah, Salt Lake City, UT, 2003.
Dissertation: “Joint Iterative Detection for Random Coded Code-Division Multiple-Access”
•    B.S., Electronics Engineering, Tsinghua University, Beijing, China, 1998.
