CWI researcher receives another international best paper award for his work
Dr Michalis Matthaiou, a researcher at the Centre of Wireless Innovation (CWI) at Queen’s University Belfast, won Best Paper Award at the 2018 International Conference on Wireless Communications and Signal Processing (WCSP) in Hangzhou, China.
This conference aims to provide a forum that brings together International researchers from academia and practitioners in industry to meet and exchange ideas and recent research work on all aspects of wireless communications and signal processing.
Dr Matthaiou worked alongside Dr Pei Liu, Dr Kai Luo, Dr Da Chen and Dr Tao Jiang from Huazhong University of Science and Technology to produce this paper entitled “Spectral Efficiency Analysis of Multi-Cell Massive MIMO Systems with Ricean Fading”.
Massive multiple-input multiple-output (MIMO) is the most promising wireless technology for the 5G era (2020 and beyond).
With massive MIMO, future base stations will be equipped with hundreds of low-power antennas to serve dozens of users. This paper presents a holistic spectral efficiency analysis for massive MIMO in Ricean fading statistics.
The paper generalizes a stream of recent papers on the same topic and presents new, tractable theoretical expressions for the achievable spectral efficiency.
The theoretical findings of this paper, corroborated with numerical simulations, show that in pure line-of-sight conditions the pilot contamination effect, which has been identified as a fundamental limitation in massive MIMO, is removed for high number of antennas.
Dr Matthaiou commented: “It was an honour to receive this award for my work in Massive MIMO. This event presents a great opportunity to meet with some of the best researchers and industry professionals in the field of wireless communications and signal processing.Over the last decade there has been a massive growth in the number of connected wireless devices. Billions of devices are now connected and managed by wireless networks which has resulted in increasing demands for wireless throughput.I look forward to continuing my research in Wireless Innovation and Massive MIMO to meet the demands of the 5G era."
