Brief Biography:

Yik-Chung Wu received the B.Eng. (EEE) degree in 1998 and the M.Phil. degree in 2001 from the University of Hong Kong (HKU).  He received the Croucher Foundation scholarship in 2002 to study Ph.D. degree at Texas A&M University, College Station, and graduated in 2005.  From August 2005 to August 2006, he was with the Thomson Corporate Research, Princeton, NJ, as a Member of Technical Staff.  Since September 2006, he has been with HKU, currently as an Associate Professor.  He was a visiting scholar at Princeton University, in summer 2011.

His research interests are in general area of signal processing and communication systems, and in particular distributed signal processing and communications; optimization theories for communication systems; estimation and detection theories in transceiver designs; and smart grid.  Dr. Wu is currently an Editor for IEEE Communications Letters, Journal of Communications and Networks, and IEEE Transactions on Communications.  He was a TPC member for over 10 IEEE major conferences.  He received three best paper awards in international conferences.  More details are included in his Curriculum Vitae.

Research:

    My research interests are in the general area of signal processing and communication systems, and in particular receiver algorithm design, synchronization techniques, channel equalization, software radio, OFDM, MIMO, cooperative systems, Bayesian inference, Monte Carlo statistical methods, and low-complexity implementation of DSP algorithms.  Some of my current research topics are listed below:

• Time synchronization for wireless sensor networks
• Robust transceiver design for cooperative communication systems
• Channel estimation and data detection for high mobility systems
• Smart Grid research

Previous research topics:

• CFO and channel estimation for single user and multi-users OFDM systems
• Symbol timing estimation and resynchronization for cooperative communication systems
• Symbol timing estimation in linear and nonlinear modulations
• Symbol timing estimation in MIMO systems
• Frame/Symbol synchronization for IEEE 802.11a (OFDM-based) WLANs
• Efficient implementation of DSP algorithms
• Software radio
• Markov based packet erasure channel modeling
• Mobile digital video broadcasting systems (DVB-H, A-VSB, TDS-OFDM)

To prospective students:    I am actively recruiting research students (mainly Ph.D.) for topics on communications and signal processing.  I am looking for students who are self-motivated, have a strong background in mathematics, and signal processing.  Due to the large amount of requesting email, I can only reply to students who can articulate their suitability in my group.  Thank you very much for your interest.

Teaching:

    ELEC1611  Circuit theory and digital logic (Fall06, Spring07, Fall07)

    ENGG1008 Electric circuit and digital logic (Fall 08, Spring 09, Fall 09)

    ELEC1306  Electric and Electronic Circuits (Spring 2011)

    ENGG1003 Engineering Mathematics (Fall 2011)

    ELEC8003  Linear algebra for signal processing (Spring08, Spring 11, Spring 13)

    ELEC8505  Probability and Random Processes (Spring 10, Spring 12)

    MATH1853 Linear algebra, probability and statistics (Fall 12)

Social Service:

In Aug 2009, I led a group of EEE students to Deyang, a rural village in Sichuan, to install an E-learning laboratory for a reconstructed primary school.  The original primary school building was destructed by the devastating earthquake on 12 May 2008.  This is a collaborative project by engineering professionals and charity organizations from Hong Kong.  The project rebuilt the whole teaching building from ground up, equipping it with quake-proof design, and up-to-date teaching technologies.
