Professor Y. Jay Guo is a Fellow of the Australian Academy of Technological Sciences and Engineering (ATSE), a Fellow of IEEE and IET. Currently, he serves as the Director of Global Big Data Technologies Centre (GBDTC) and Distinguished Professor at the University of Technology Sydney (UTS), Australia. Prior this this appointment, he served as Director of a number of research portfolios in CSIRO, Australia. Before joining CSIRO, Prof Guo worked as a R&D leader in the European mobile communications industry for eight years. His research interest includes reconfigurable antennas, large scale wideband and conformal antenna arrays, base-station technologies, and advanced wireless communications and sensing systems.
The massive antenna array is one of the key technologies to enable mm-wave communications for 5G and beyond. Unfortunately, the implementation of full massive MIMO arrays proved to be too costly and unnecessary, and the wireless industry is adopting hybrid antenna arrays as a practical approach going forward. Based on our pioneering work on hybrid antenna arrays reported nearly a decade ago, we shall present our recent research on new massive hybrid array architectures. These include hybrid antenna arrays of localized phased arrays, lenses, Butler matrices and reconfigurable Butler matrices. We shall report new signal processing algorithms for angle of arrival (AoA) estimation and beam synthesis to support these hybrid array architectures. A comparison on the power consumption of these different hybrid beamforming architectures will also be reported.
