Brief Biography: Yik-Chung Wu obtained the B.Eng. (EEE) degree in 1998 and the M.Phil. degree in 2001 from The University of Hong Kong (HKU).  After graduation from Master degree, he was a research assistant in the same university.  He started his Ph.D. degree in 2002 at the Texas A&M University, USA and obtained the Ph.D. degree in 2005.  During his study at Texas A&M University, he was fully supported by the Croucher Foundation scholarship.  From Aug. 2005 to Aug. 2006, he was with the Thomson Corporate Research, Princeton, NJ, as a Member of Technical Staff.  Since Sep. 2006, he has been with the University of Hong Kong as an Assistant 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 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.  Dr. Wu is currently an Editor for IEEE Communications Letters, and Journal of Communications and Networks.  He was a TPC member for over 10 IEEE major conferences.  He received two 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:

• CFO and channel estimation for single user and multi-users OFDM systems
• Time synchronization for wireless sensor networks
• Symbol timing estimation and resynchronization for cooperative communication systems
• Robust transceiver design for cooperative communication systems

Previous research topics:

• 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 various projects on communications and signal processing.  I am looking for students who are self-motivated and have a strong interest in wireless communications.  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.

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.
