Analysis and Design for Cell-free Massive MIMO.

Hien Ngo has studied many aspects of Communications Technology in Universities all over the world, and has obtained BSc, MSc and PhD qualifications.

Hien is currently a Lecturer at the Institute of Electronics, Communications & Information Technology (ECIT), Queen’s University Belfast. Their general research interests are the application of information theory and signal processing to develop novel, low-cost, and eco-friendly solutions for future wireless systems.

Hien has co-authored many research papers in wireless communications and co-authored the Cambridge University Press textbook Fundamentals of Massive MIMO (2016). Hien has received three prestigious prizes: the IEEE Stephen O. Rice Prize in 2015, the IEEE Leonard G. Abraham Prize in 2017, and the Best PhD Award from EURASIP in 2018. Hein currently serves as Editor for the IEEE Wireless Communications Letters and the Digital Signal Processing. Hien was Guest Editor for the IET Communications and the IEEE Access in 2017.

Hien aims to develop a totally new mobile network, called cell-free massive multiple-input multiple-output (MIMO). Over the past 40 years, mobile networks are based on cellular topologies where the land area is divided into cells, each is served by a base station. However, cellular networks are running out of capacity and are not suitable for future wireless systems which have to manage billions of devices at the same time, with many applications including machine-type communications, Internet of Things, Smart X. Different from cellular networks, in cell-free massive MIMO there are no cells, i.e. many (thousands or more) access points distributed over a large area jointly serve many users. This system can improve data speed, reliability and connectivity, and hence, meet demands of future wireless systems.

With the Future Leaders Fellowship award, Hein will build a strong research team, who will work directly with researchers at ECIT and collaborate with world-leading researchers in the field from both academia and industry to further improve this new mobile network. Hein plans to exploit/model new methods of signal processing for cell-free massive MIMO before moving to test successful models in the laboratory.
