Abstract:

Millimeter wave (mm-wave) technology has been considered as a very promising candidate for 5G cellular communications and other high speed wireless links. To combat the significant propagation loss for mm-wave transmission, a large antenna array with many antenna elements is necessary for a mm-wave radio. Since a full digital array is impractical due to the space constraint and implementation cost, a hybrid array which consists of multiple analog subarrays, each having only one digital chain, will be a more feasible solution. Different from those well-studied techniques in either a full analog or digital array, angle-of-arrival (AoA) estimation in a mm-wave hybrid array is a very challenging problem which forms the basis for many advanced signal processing applications such as multiple input multiple output (MIMO) beamforming and spatial division multiuser access. This presentation gives an introduction to some fundamental aspects on mm-wave propagation, massive MIMO, and hybrid array. More focus is placed on the AoA estimation and beamforming techniques for localized hybrid array using differential beam search (DBS) algorithm and an improved adaptive searching and tracking (AST) algorithm.  

Bio:

Xiaojing Huang (M’99, SM’11) received his Bachelor of Engineering, Master of Engineering, and Ph.D. degrees from Shanghai Jiao Tong University, Shanghai, China, in 1983, 1986, and 1989, respectively, all in electronic engineering. With over 26 years of combined industrial, academic, and scientific research experience, he has published over 230 book chapters, refereed journal and conference  papers, and major commercial research reports, and filed 29 patents. He is currently a professor of information and communications technology in the School of Computing and Communications and the program leader for mobile sensing and communications in the Global Big Data Technologies Centre at the University of Technology, Sydney (UTS), Australia. He is also an Adjunct Professor at Macquarie University, Sydney, Australia. Before joining UTS, he had been a principal research scientist at Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia, and the project leader of CSIRO microwave and mm-wave backhaul projects since 2009, an associate professor at University of Wollongong, Australia, since 2004, and a principal research engineer at Motorola Australian Research Centre since 1998. Prof. Huang is a recipient of CSIRO Chairman’s Medal and the Australian Engineering Innovation Award in 2012 for exceptional research achievements in multi-gigabit wireless communications.
