 Dr Wei Liu
(BSc, LLB, MPhil, PhD, CiLT, SMIEEE)

I received my BSc in Space Physics (minor in Electronics) in 1996 and LLB in Intellectual Property Law in1997 from Peking University, China (I passed the Lawyer Qualification Examination of China in 1997 and practised as a trainee lawyer and then received my full lawyer's licence in 1999), MPhil from the Department of Electrical and Electronic EngineeringUniversity of Hong Kong, in 2001, PhD in 2003 from the School of Electronics and Computer ScienceUniversity of Southampton, U.K. I then worked as a postdoc first in Southampton and later in the Department of Electrical and Electronic EngineeringImperial College London. In September 2005, I joined the Communications Research GroupDepartment of Electronic and Electrical EngineeringUniversity of Sheffield as a lecturer, and then promoted  to senior lecturer in January 2015.

My research interests cover a wide range of topics in signal processing, in particular including sensor (antenna, hydrophone, microphone, seismometer, etc.) array signal processing (beamforming, direction of arrival estimation, tracking and localisation), blind signal processing (source separation/extraction), multirate signal processing (filter banks and wavelets), and their various applications, such as wireless communications, satellite navigation, radar, sonar, biomedical engineering, speech enhancement, human computer interface, big data analytics, and renewable energy exploitation.

I received two “Best Paper" awards (“Improving SSVEP-BCI Performance Using Pre-Trial Normalization Methods” from the 2017 IEEE International Conference on Cognitive Infocommunications, and “Reduced Complexity MIMO Receiver with Real-Valued Beamforming” from the 2015 15th IEEE International Conference on Computer and Information Technology), and one “Excellent Paper" award (“Robust DOA Estimation for a MIMO Array Using Two Calibrated Transmit Sensors” from the 2013 IET International Radar Conference).
